11 He received the sign of circumcision as a seal of the righteousness that he had by faith while he was still uncircumcised. The purpose was to make him the father of all who believe without being circumcised, so that righteousness would be counted to them as well, 12and to make him the father of the circumcised who are not merely circumcised but who also walk in the footsteps of the faith that our father Abraham had before he was circumcised. – Romans 4:11-12
I always did like the song Father Abraham. But it isn’t just a cute kids song, it is a solid biblical truth. Father Abraham has many sons (and daughters), all of us who live by faith the same way that he did. Paul here says that it involves walking in the footsteps of Abraham. It isn’t about an outward sign or symbol, it is about a way of life. The life of faith is walking in God’s Ways according to His Word. Do the real walk of life today.
