If a person believes in Christ Jesus, it doesn’t matter whether they’re circumcised or not. The only thing that matters is faith expressing itself through love.
There’s only one God. He’ll make those who are circumcised right with himself by faith, and he’ll make those who aren’t circumcised right with himself by that same faith.
So anyone who sets aside one of the least of the commands and teaches others to do the same will be called the least in the kingdom of heaven. But anyone who practices and teaches the commands will be called great in the kingdom of heaven.
