10 But when did this happen? Was it before or after Abraham was circumcised? Of course, it was before.
11 Abraham let himself be circumcised to show he had been accepted because of his faith even before he was circumcised. This makes Abraham the father of all who are acceptable to God because of their faith, even though they are not circumcised.
12 This also makes Abraham the father of everyone who is circumcised and has faith in God, as Abraham did before he was circumcised.
13 God promised Abraham and his descendants that he would give them the world. This promise wasn't made because Abraham had obeyed a law, but because his faith in God made him acceptable.
14 If Abraham and his descendants were given this promise because they had obeyed a law, then faith would mean nothing, and the promise would be worthless.
15 God becomes angry when his Law is broken. But where there isn't a law, it cannot be broken.
16 Everything depends on having faith in God, so that God's promise is assured by his gift of undeserved grace. This promise isn't only for Abraham's descendants who have the Law. It is for all who are Abraham's descendants because they have faith, just as he did. Abraham is the ancestor of us all.
