What then shall we say that Abraham, our forefather according to the flesh, discovered in this matter? If, in fact, Abraham was justified by works, he had something to boast about—but not before God. What does Scripture say? “Abraham believed God, and it was credited to him as righteousness.” Now to the one who works, wages are not credited as a gift but as an obligation. However, to the one who does not work but trusts God who justifies the ungodly, their faith is credited as righteousness.
Firstly, Paul says that justification comes to use as a gift and not a wage. The very nature of gifts is that they are not earned – they come to us freely, out of the generosity of the giver. We don’t work for them. Instead, says Paul, the one who is justified (or ‘counted as righteous’) is the one who does not work, but simply trusts in “him who justifies the ungodly”.
This is the astonishing news of the gospel: that God justifies not the good or the moral or the hard-working or the deserving but “the ungodly”. Paul is very explicit about it. He says that justification comes to “one who does not work”. We Australians have a word for those who choose not to work: we call them ‘bludgers’. The apostle is saying in effect that justification is only for those who are prepared to ‘bludge’ on the mercy of God. In other words, it is for those who realize that their good works will never justify them before God, no matter how hard they try, and so who trust God and take him at his word rather than trust their good works.
To further demonstrate the point, Paul retraces Abraham’s story and asks whether God declared Abraham to be justified before or after he was circumcised (circumcision being one of the classic ‘works of the law’). Did the good work of circumcision play a part in his justification or not? The answer is No! God declared Abraham to be righteous simply because he trusted God’s word. pg 67
Faith is a personal attitude of trust and dependency. In fact, the word ‘trust’ is a good everyday replacement for ‘faith’ in most places where you meet the word in the Bible. Faith is by no means just an intellectual assent that something is true. It is a personal trust that something is true. But trust in what?
“Some trust in chariots and some in horses,” says the psalmist, “but we trust in the name of the Lord our God” (Ps 20:7).
‘Faith’ in the Bible is trust in God, and especially in the promises of God – such as those promises that come to us in the gospel. Faith is an open hand ready to receive what God promises to give us through Christ. By its nature, faith offers nothing and contributes nothing. It simply trusts in Another, and receives salvation from him as a free gift. Faith points away from itself and says, “I can’t take away my own sins, or atone for them. Christ alone can do that for me.”
Abraham modelled that faith by taking God at his word. In Romans 4, Abraham’s faith is defined in terms of being “fully convinced that God was able to do what he had promised” (Rom 4:21). Faith is about taking God at his word. And this, says Paul, is the only way a person can be justified – not through doing sufficient good works to earn God’s approval, but by putting our trust in what Jesus has done on the cross to wipe out all our sins. pg 69
There is an old line about the difference between religion and Christianity that I have always loved: religion is spelt ‘do’; Christianity is spelt ‘done. He done it! It may be bad English, but it’s great theology.
