Romans 4:13 – For the promise to Abraham and his offspring that he would be heir of the world did not come through the law but through the righteousness of faith.
We might say that in these next few verses Paul is ‘beating a dead horse’. In other words, he continues proving that justification before God cannot be through the law, but only through faith. 
It may seem tedious to us to see this over and over in different ways, but it is actually very important because it firmly and fully establishes the doctrine of salvation by faith in Christ, which is the very foundation of the Christian life. This message needed to be set forth in a manner that could never be questioned or challenged, and Paul does exactly that.
Again, we must remind ourselves that the early New Testament church had some serious issues with unity between Jews and Gentiles. If God did not fully and firmly establish that these two groups were both equally sinful in his sight and equally justified in the same manner (apart from the law), we may very easily wound up with two churches – a Jewish one and a Gentile one.
With this in mind, let’s see what the apostle has to say.
The promise: The promise in verse 13 is that Abraham would be the heir of the world. What does that mean?
It can’t mean that he inherited a title or kingship making him the supreme ruler of the earth, because we know that did not happen. As far as we know, he didn’t rule over anything other than his own household (and even then, his wife clearly had some influence).
It can’t mean that his father passed down ownership of vast amounts of land and resources to him, because that didn’t happen either. As far as we know, the only land Abraham owned was a tiny, insignificant burial cave in the land of Canaan, which he bought from the Hittites (Genesis 23).
How can Paul say that Abraham was heir of the world?
He is indicating that Abraham would be the channel through which the mercy of God would be communicated to the world. This happens in two ways.
One, his example of obtaining justification by faith shows the rest of mankind how to obtain that same gift from God.
Two, he is the ancestor of the Messiah, who is the heir and ruler of the world both physically and spiritually:
Hebrews 1:2 – …but in these last days he [God] has spoken to use by his Son, whom he appointed the heir of all things, through whom also he created the world.
We might say that Abraham is represented as having the world as his inheritance because it was through his offspring (Jesus) that the whole world obtained mercy and blessing; in a sense he passed that blessing down to future generations as a kind of inheritance.
We might also say it this way: Heir of the world is equivalent to being the father of many nations; Abraham was the representative of all the believing world and made the heir of an inheritance (justification by faith) which would be made available to the world in general (all who believe, both Jew and Gentile).
Here is something that will make your day: As if the blessing of justification weren’t enough, God gives us even more. In Romans chapter 8, Paul will show that Jesus is the Son of God and he owns all things. Because he made us children of God too (through justification), then we are considered co-heirs with Jesus!
Romans 8:16-17 – The Spirit himself bears witness with our spirit that we are the children of God, and if children, then heirs – heirs of God and fellow heirs with Christ, provided we suffer with him in order that we may also be glorified with him.
Just let the implication of that sink in for a moment!
To Abraham and his offspring: The promise was to Abraham and his descendants. Abraham has two lines of descent. In the natural realm, the Jews were his physical children/offspring. In the spiritual realm, all those who grasp the promises of God through faith are his spiritual children/offspring.
That he would be heir of the world: An heir is a person who is legally entitled to take possession of an estate after the death of its owner. An estate can include many things, like money, possessions, land, authority or even titles.
In this case, the world or the earth is the estate which the offspring of Abraham will inherit.
First, let’s look at this from the viewpoint of Abraham’s physical descendants, the Jews. If you mentioned ‘inheriting the world’ their minds immediately jumped to their inheritance known as the Promised Land – the choicest spot of ground on earth. How did they obtain that inheritance?
The first step in giving them this land for an inheritance was to free them from slavery to Egypt. This deliverance was not accomplished by the power of the Jews; they had absolutely no way to free themselves. Their only hope for release was to trust/have faith in the promise of God that he would bring them out of Egypt by his might and power, as he said he would:
Exodus 6:6 – Say therefore to the people of Israel, ‘I am the Lord and I will bring you out from under the burdens of the Egyptians, and I will deliver you from slavery to them, and I will redeem you with an outstretched arm and with great acts of judgment.’
Once they were freed by the miraculous power of God, he led them through the wilderness to the land he set aside for them. He was continuously with them in all of their battles, until they obtained victory and possessed the land:
Exodus 6:8 – ‘I [God] will bring you into the land that I swore to give to Abraham, to Isaac, and to Jacob. I will give it to you for a possession. I am the Lord.’
Even a cursory reading of Old Testament history shows that the Jews did not accomplish this victory through their own power, or through their adherence to the law. If anything, history shows us how unworthy and helpless the Jews were; their victory was obtained only through the mercy and grace of God.
Now let’s look at this issue from the viewpoint of Abraham’s spiritual descendants, those who accept justification by faith in Christ Jesus. As you know, events of the Old Testament are shadows or types of God’s plans under the new covenant of the gospel.
For example, slavery in Egypt was a picture of our bondage to sin. None of the Jews could rescue themselves from the grip of the Egyptians. In the same way, no person can rescue themselves from sin through their own works or adherence to the law. The only way for the Jews to be delivered from Egypt was to trust in the promises of God. The only way for mankind to be delivered from sin is to have faith in the promise of the Redeemer.
In the natural realm, Israel had to fight to obtain the full expanse of the Promised Land. God assisted them in this fight; victory was obtained through him (Joshua 10:24-25). In the spiritual realm, Christians fight to expand the kingdom of God on earth:
Matthew 11:12 – From the days of John the Baptist until now the kingdom of heaven has suffered violence, and the violent take it by force.
God assists us in this fight; victory is obtained through him. 
The Promised Land was a place that flowed with milk and honey; it was the place of great blessing and peace. The Promised Land is a type/picture of heaven (Hebrews 11:8-10, 16).
At the perfect time, God brought the physical descendants of Abraham into possession of the Promised Land. Likewise, at the perfect time, God will bring the spiritual descendants of Abraham into heaven to be with him, where we will experience full and complete eternal blessings and peace.
Here is the point: No Jew would ever claim that deliverance from Egypt and possession of the Promised Land came through their own abilities or through perfect obedience to the commands and laws of God. That would be utter blasphemy. They acknowledged, without question, that they received these blessings by faith – trusting and leaning on the promises of God.
This example in the natural realm shows that the spiritual offspring of Abraham will receive forgiveness of sin (freedom from the curse of the law) and entrance to heaven by faith in the promised Messiah.
It works like this: Step one – faith in the promise of God (justification through the Messiah). Step two – receiving the imputed righteousness of Christ. Step three – gaining access to the Messianic kingdom and all its privileges and blessings.
Did not come through the law: The promise of inheriting the earth did not come through observance of the law; it was independent of both the Mosaic law and the rite of circumcision. This has already been unquestionably proved by Paul.
But through the righteousness of faith: The promise of Abraham’s descendants inheriting the earth can’t be limited to his natural Jewish descendants inheriting Canaan. That example is far too small to be the complete fulfillment of God’s promise. Rather, that inheritance in the natural realm was a picture of Abraham’s spiritual descendants who will inherit all things (including heaven) by faith through their relationship to Christ.
Galatians 3:28-29 – There is neither Jew nor Greek, there is neither slave nor free, there is no male and female, for you are all one in Christ Jesus. And if you are Christ’s, then you are Abraham’s offspring, heirs according to promise.
So, using the type/shadow/example given in the historical context of the Old Testament, Paul shows that heirship was given to Abraham, not because he deserved it by keeping the law, but because he had faith in the promises of God. It was faith that justified him in God’s sight.
Hence, it logically follows that because justification is a matter of faith based only on the goodness and mercy of God, then that benefit must belong to the Gentiles just as much as the Jews.
Romans 4:14 – For if it is the adherents of the law who are to be the heirs, faith is null and the promise is void.
As we have noted before, faith and works are opposites. If people could obtain righteousness and life by works/adherence to the law, then faith serves no purpose – it is redundant, useless and futile.
If salvation is by works, then there is no reason for God’s Son to die a humiliating and painful death on the cross and no reason for men to believe in him.
As Paul has already proven, you can inherit under the law – but your inheritance will consist of bondage to sin and a sentence of eternal death. Faith, on the other hand, is the key to the inheritance of life and blessing. It unlocks grace and grace is open to all mankind, both Jews and Gentiles.
Romans 4:15 – For the law brings wrath, but where there is no law there is no transgression.
Where there is no law, there is no transgression: Suppose you are driving in through a nearly deserted area, and there is no posted speed limit. Under those conditions, you could go as fast or slow as you wish, because there is nothing which says you can’t do so. If there was a police officer nearby, he would not be able to give you a ticket, because you weren’t breaking any speed limit laws.
In the same way, if God had not given us the law, then there wouldn’t be any rules to break, and so there couldn’t be any sin. If there was no sin, then naturally there couldn’t be any penalty for doing whatever you wanted to do. 
The law brings wrath: However, as we are all well aware, every city has speed limit laws. If the speed limit is 35 mph and you choose to drive 70 mph, the authorities can determine that you broke the law. At that point, they have the right to issue you a citation, which declares your guilt and outlines your punishment (a fine, points on your license, etc).
In the same way, God’s law is important because it establishes the baseline obligations of the moral life God demands of us. When our actions are compared to his law, our guilt becomes evident and the penalty of the law automatically pronounces judgement against us.
So obviously, the law has limits. By its very nature, it can only condemn us. Specifically, the law has the power to do three things:
- One, it uncovers or exposes our sin. It does this by comparing our lives to the commandments of God.
- Two, it convicts us or pronounces us guilty of breaking God’s laws.
- Three, it sentences us to the correct punishment – it puts us under the wrath of God which results in spiritual death.
Simply stated, the thing which condemns us does not have the power to justify us. Because the law condemns the sinner for his transgressions, it can never, ever be the instrument or means of our justification. It can never, ever offer us grace or mercy. It can show us what holy living should look like, but it cannot give us the power to live holy lives.
If faith and works of the law are opposites, and the law only has the power to condemn, then by default faith is the sole means of salvation/justification.
Romans 4:16 - Therefore it is of faith, that it might be by grace; to the end the promise might be sure to all the descendants; not to those only who are of the law, but to those also who are of the faith of Abraham; who is the father of us all,
Therefore: In view of the argument or line of reasoning that has been presented in verses 13-15, we can reach a logical conclusion.
It is of faith that it might be by grace: Justification by faith is the plan which God has devised for the salvation of mankind. This means that redemption is solely based on God’s grace and mercy; it has nothing to do with our efforts. 
To the end: The reason why justification is by grace and not works is so the promise might be sure and that it might be open to all (see below).
The promise might be sure: If we obtained the promises of God by works, then we would always be unsure/uncertain if we had them or if we were even able to receive them because of our weakness and failure in adhering to the law. This would naturally produce uncertainty, fear of failure, inactivity/timidity, and frustration.
But thankfully, that is not the case. As Paul once again points out based on the logical arguments presented here, the promise of justification is built upon the foundation of God’s mercy, favor and grace. Because God never fails or changes, Paul could confidently say that the promise is sure or guaranteed or firmly established. We never have to wonder about our salvation; it is guaranteed as long as we trust in Christ.
To all descendants, not to those only who are of the law: By now we have figured out that those under the law are the Jews. The promise of justification is still open to the Jews, if they are willing to let go of their works and accept it by faith. The good news is that the gift of righteousness before God is no longer limited just to them.
But to those also who are of the faith of Abraham: Since Abraham was justified by faith apart from the law, then Gentiles (who are also apart from the law) can be justified in the same way.
The father of us all: Once again, Paul establishes the fact that Abraham is the father of all who believe – both Jews and Gentiles.
And once again, we have cause to marvel at the wisdom and sovereignty of our God!
He knew there was no way we could be justified by our own efforts. He also knew that the price of sin must be paid; his holiness and perfection would never allow for anything but complete justice.
By having his Son pay the price of our sin and by giving us the opportunity to embrace Christ’s righteousness through faith, God has perfectly displayed his mercy and grace to us while fully satisfying the requirements of divine justice.
Not only that, his process of justification through faith includes ALL mankind – all those under the law as well as all those outside of his law. Praise his glorious name!
Let me offer you some encouragement and relief:
Through Christ we have become the children of God, which makes us heirs of all his blessings. These include his glory (John 17:22), his riches (II Corinthians 8:9) and ‘all things’ (Hebrews 1:2).
We will ultimately receive the entirety of our inheritance once we reach heaven:
I Peter 1:3-4 – Blessed be the God and Father of our Lord Jesus Christ! According to his great mercy, he has caused us to be born again to a living hope through the resurrection of Jesus Christ from the dead, to an inheritance that is imperishable, undefiled, and unfading, kept in heaven for you…
So be encouraged today. In this life you will have difficulties and trials but remember – you are a child of God. You are precious in his sight, and you will inherit the kingdom of heaven.
Let me offer you some strength:
Abraham was a spiritual example to all his descendants, both physical and spiritual. You can be the same. In fact, you probably already are.
If you consider yourself a Christian the people around you (family, friends, colleagues at work, etc.) are watching your life, whether you realize that or not. This is especially true of those who are not yet Christians.
They are looking to see if your actions line up with your words. They are looking to see if faith in Christ produces joy and peace or the same old turmoil and anxiety they have now. They want to know if prayer really works, or it’s just a farce. They want to know if the God you serve is 100% dependable or if he only shows up for you occasionally.
So be aware of your example. Does your daily life mirror the hope and victory of Christ, or does it reflect the same broken promises found in the world? Does your conversation line up with the victory Christ procured for us, or do your words reflect defeat?
No one is perfect all the time. I understand that, because I fail too. Nevertheless, today is a good day to remind yourself that you are an Abraham – so let’s strive to be the example that draws others into the kingdom!


















(both Jews and Greeks/Gentiles) is essentially wicked. He is mainly pointing this out for the benefit of the Jews. They were more than happy to admit that the Gentiles were wicked, but they erroneously believed that they were justified in God’s sight because they were his people. 

sight by keeping the law, Paul now offers a solution to the problem – justification apart from the law; justification by faith through the imparted righteousness of Jesus Christ.
