In the last portion of 1 Corinthians 7, Paul talks about contentment. In dealing with these matters he says what we really need for contentment is to abide in whatever calling God has called us to. If God has called you to marriage, be content with the marriage. Use it for his glory and make the marriage everything that God can possibly make the marriage be. If, on the other hand, at this point in your life, God has called you to a single state, do not try to be married, because God’s grace is sufficient for the single life. God will bless it, too.
