Brothers and sisters, with all my heart I long for the people of Israel to be saved. I pray to God for them.
I can give witness about them that they really want to serve God. But how they are trying to do it is not based on what they know.
They didn't know how God makes people right with himself. They tried to get right with God in their own way. They didn't do it in God's way.
Christ has completed the law. So now everyone who believes can be right with God.
Moses explained how the law could help a person do what God requires. He said, "The one who does those things will live by them."(Leviticus 18:5)
But the way to do what God requires must begin by having faith in him. Scripture says, "Do not say in your heart, 'Who will go up into heaven?' "(Deuteronomy 30:12) That means to go up into heaven and bring Christ down.
