Scripture plainly reveals that God repeatedly calls for His people to separate from the world. This separation extends to every aspect of life, especially including the marriage bond. Why? Because God knows the very real danger that unbelievers pose to believers by drawing them away from Him (Deuteronomy 7:3-4; Judges 3:6-7; 1 Kings 11:2). This is why God specifically instructed His people in both the Old and New Testament to marry among themselves (Jew with Jew and Christian with Christian). The nation of Israel was forbidden to yoke up with the surrounding nations because Israel would adopt heathen practices and the worship of false gods (Exodus 34:15-16). Though God’s commands for the New Testament believer are often different from His plan for the Jew, in this aspect they remain constant and unchangeable.
Like other callings upon a person’s life, God prepares men and women for marriage. Obviously, God prepares the heart, but He also prepares other areas in order to provide for a strong home. When God created Adam, He could have immediately created Eve, but He chose to allow Adam to experience the sense of being alone. Perhaps there are other reasons, but God may have thought it wise to prepare Adam for marriage. He needed to experience life without Eve. Adam needed to come to the place where he desired companionship. He needed to be alone before he could truly appreciate a wife. In addition to the preparation of Adam’s heart, the Lord gave him a job, a means by which he could provide for Eve (Genesis 2:8-9, 15). All of these preparations were necessary for a strong marriage relationship.
