There are many rebellious people who try to deceive others with smooth talk. This is especially true of those who say that Gentiles who believe in Jesus have to be circumcised.
Make sure that no one makes you their prisoner through false and deceptive reasoning, through ideas that depend on human teachings and the basic spiritual powers of this world rather than on Christ.
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.
