God has not rejected his people whom he knew long ago. Don’t you know what Elijah says in the Scripture passage when he complains to God about Israel? He says,
Abraham’s faith was the basis of his approval by God while he was still uncircumcised. The mark of circumcision is the seal of that approval. Therefore, he is the father of every believer who is not circumcised, and their faith, too, is regarded as the basis of their approval by God.
Are only the circumcised people blessed, or are uncircumcised people blessed as well? We say, “Abraham’s faith was regarded as the basis of God’s approval.”
For example, Scripture says to Pharaoh, “I put you here for this reason: to demonstrate my power through you and to spread my name throughout the earth.”
The Scripture passage came true. It says, “Abraham believed God, and that faith was regarded as the basis of Abraham’s approval by God.” So Abraham was called God’s friend.
