Because they did not know the way that God makes people right with him, they tried to make themselves right in their own way. So they did not accept God's way of making people right.
Christ ended the law so that everyone who believes in him may be right with God.
Moses writes about being made right by following the law. He says, "A person who obeys these things will live because of them."
But this is what the Scripture says about being made right through faith: "Don't say to yourself, 'Who will go up into heaven?' " (That means, "Who will go up to heaven and bring Christ down to earth?")
"And do not say, 'Who will go down into the world below?' " (That means, "Who will go down and bring Christ up from the dead?")
This is what the Scripture says: "The word is near you; it is in your mouth and in your heart." That is the teaching of faith that we are telling.
If you use your mouth to say, "Jesus is Lord," and if you believe in your heart that God raised Jesus from the dead, you will be saved.
We believe with our hearts, and so we are made right with God. And we use our mouths to say that we believe, and so we are saved.
As the Scripture says, "Anyone who trusts in him will never be disappointed."
That Scripture says "anyone" because there is no difference between those who are Jews and those who are not. The same Lord is the Lord of all and gives many blessings to all who trust in him,
as the Scripture says, "Anyone who calls on the Lord will be saved."
