No believer should knowingly marry an unbeliever (2 Corinthians 6:14). Additionally, the unmarried should look for other strengths and weaknesses in a prospective spouse before agreeing to marriage. Oftentimes, these strengths and weaknesses can be seen by interaction with the other’s parents. Isaac lied about Rebekah (Genesis 26:6-7) just as his father Abraham lied about Sarah (Genesis 12:10-13; Genesis 20:1-2). Solomon’s weakness for women (1 Kings 11:1) was first witnessed in his father David (2 Samuel 11:1-4). Rachel learned deception (Genesis 31:32-35) by watching her father act deceptively (Genesis 29:25). A careful observation of parents can reveal prospective problems in a future spouse.
The psalmist proclaims: “Behold, how good and how pleasant it is for brethren to dwell together in unity!” Unlike the unity of unbelievers and the heathen, the Lord rejoices in the righteous unity of His people. King David was someone who knew and experienced the difficulties of division. He spent a great deal of his life running from a king and those who were against him. Even in the beginning of his reign, the people were divided (2 Samuel 2:8-11). It was not until 7 1/2 years later that the people were united in David (2 Samuel 5:1-5). When the people dwelt in unity, David rejoiced. He likened it to the source of spiritual life for the nation of Israel, the priesthood (Psalm 133:2), and to the source of physical life in the dew of Hermon (Psalm 133:3). In other words, the right kind of unity gave life and hope to the nation!
