We know that the law's commands are for those who have the law. This stops all excuses and brings the whole world under God's judgment,
because no one can be made right with God by following the law. The law only shows us our sin.
But God has a way to make people right with him without the law, and he has now shown us that way which the law and the prophets told us about.
God makes people right with himself through their faith in Jesus Christ. This is true for all who believe in Christ, because all people are the same:
All have sinned and are not good enough for God's glory,
and all need to be made right with God by his grace, which is a free gift. They need to be made free from sin through Jesus Christ.
God gave him as a way to forgive sin through faith in the blood of Jesus' death. This showed that God always does what is right and fair, as in the past when he was patient and did not punish people for their sins.
And God gave Jesus to show today that he does what is right. God did this so he could judge rightly and so he could make right any person who has faith in Jesus.
So do we have a reason to brag about ourselves? No! And why not? It is the way of faith that stops all bragging, not the way of trying to obey the law.
A person is made right with God through faith, not through obeying the law.
Is God only the God of the Jews? Is he not also the God of those who are not Jews?
