If you do this, you will be true children of your Father in heaven. He causes the sun to rise on good people and on evil people, and he sends rain to those who do right and to those who do wrong.
And Abraham is also the father of those who have been circumcised and who live following the faith that our father Abraham had before he was circumcised.
So people receive God’s promise by having faith. This happens so the promise can be a free gift. Then all of Abraham’s children can have that promise. It is not only for those who live under the law of Moses but for anyone who lives with faith like that of Abraham, who is the father of us all.
