A man who loses hope loses his primary motivation for doing right and living holy. The Bible reveals what men do when they have no hope: “let us eat and drink; for to morrow we die” (1 Corinthians 15:32). If there is no hope in a resurrection, man sees no reason to cease to go after his strange gods (Jeremiah 2:25) or follow “the imagination of his evil heart” (Jeremiah 18:12). If there is no judgment after death, or if the Lord is not soon returning, then the greatest impetus for living the Christian life is lost. Man needs a special motivation to help him to live a life of purity. He should live in purity because He loves the Lord. Yet, the answer lies in the fact that the Lord is coming soon, and man will stand before Him to give an account, and all those who have this particular hope will purify themselves, “even as he [Jesus] is pure.” Hope makes all the difference!
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.
