18 If any man who is a Christian has had circumcision, let him keep so; and if any man who is a Christian has not had circumcision, let him make no change. 19 Circumcision is nothing, and its opposite is nothing, but only doing the orders of God is of value. 20 Let every man keep the position in which he has been placed by God.
Matthew Henry's Commentary on 1 Corinthians 7:18-20
Commentary on 1 Corinthians 7:17-24
(Read 1 Corinthians 7:17-24)
The rules of Christianity reach every condition; and in every state a man may live so as to be a credit to it. It is the duty of every Christian to be content with his lot, and to conduct himself in his rank and place as becomes a Christian. Our comfort and happiness depend on what we are to Christ, not what we are in the world. No man should think to make his faith or religion, an argument to break through any natural or civil obligations. He should quietly and contentedly abide in the condition in which he is placed by Divine Providence.
