Chapter 3:21-26 The revelation of God’s judgement
God's saving justice was witnessed by the Law and the Prophets, but now it has been revealed altogether apart from law: God's saving justice given through faith in Jesus Christ to all who believe. No distinction is made: all have sinned and lack God's glory, and all are justified by the free gift of his grace through being set free in Christ Jesus. God appointed him as a sacrifice for reconciliation, through faith, by the shedding of his blood, and so showed his justness; first for the past, when sins went unpunished because he held his hand; and now again for the present age, to show how he is just and justifies everyone who has faith in Jesus.
]Chapter 3:27-31 What faith does
So what becomes of our boasts? There is no room for them. On what principle – that only actions count? No; that faith is what counts, since, as we see it, a person is justified by faith and not by doing what the Law tells him to do. Do you think God is the God only of the Jews, and not of gentiles too? Most certainly of gentiles too, since there is only one God; he will justify the circumcised by their faith, and he will justify the uncircumcised through their faith. Are we saying that the Law has been made pointless by faith? Out of the question; we are placing the Law on its true footing.
