Ephesians 5:18-21 ​ And do not be drunk with wine, in which is dissipation; but be filled with the Spirit, speaking to one another in psalms and hymns and spiritual songs, singing and making melody in your heart to the Lord,  giving thanks always for all things to God the Father in the name of our Lord Jesus Christ,  submitting to one another in the fear of God.

It should be recognized that every individual created by God is a diamond in the rough. Diamonds, however, need grinding and polishing to develop their beauty. For this purpose God instituted   the marriage relation as one of the central workshops in which that grinding and polishing process takes place. The dust and sparks may have to fly a bit in the workshop, but the two need each other in the refining process just as the diamond needs grindstone. And the submitting of each partner to this polishing operation is the key to both marriage and harmony and their individual development in the plan of God.  --Stanley a Ellisen (Divorce and Remarriage in the Church p32)
