Basic Bible Course on the Epistle to the Romans

The Apostle Paul has made it clear to us that no man can be justified (that is, declared righteous) on the basis of his works. For, although this possibility theoretically exists (Chapter 2:13), no one will ever achieve this, since we are by nature sinners (Chapter 3:20).

But God has found a way apart from the law (Chapter 3:21).

First read Romans Chapter 3, Verse 21 to Chapter 4, Verse 25.

The righteousness of God was already announced through the prophets of the Old Testament. We read in Isaiah 56:1:

Thus says the LORD: Keep you judgment and do righteousness; for my salvation is near to come, and my righteousness to be revealed. (Isaiah 56:1)

But now it has been "revealed" (Verse 21; Chapter 1:17).

If this righteousness is now valid without intervention of the law, on what basis can one then be justified (Verse 22)?

All the groups of people seen so far can ultimately be summed up into one group that includes a negative and a positive aspect (verses 23 and 24).

Justification comes therefore by faith (on man's part, verse 22) and by grace (on God's part, verse 24).

But how and by whom was the price paid for this (verses 24-25)?
