1 Corinthians 7:18-20
1 Corinthians 7: 18 to 20
18 If a circumcised man has accepted God's call, he should not try to remove the marks of circumcision; if an uncircumcised man has accepted God's call, he should not get circumcised.
19 For whether or not a man is circumcised means nothing; what matters is to obey God's commandments.
20 Each of you should remain as you were when you accepted God's call.
