“Don't hurt the boy or harm him in any way!” the angel said. “Now I know that you truly obey God, because you were willing to offer him your only son.”
If you are a follower of Christ Jesus, it makes no difference whether you are circumcised or not. All that matters is your faith that makes you love others.
Suppose someone disagrees and says, “It is possible to have faith without doing kind deeds.” I would answer, “Prove that you have faith without doing kind deeds, and I will prove that I have faith by doing them.”
