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.
The Bible plainly points out that God is not the author (or originator) of the confusion in the life of any believer. In fact, God desires for every individual to have clarity of mind when it comes to the truths found in His word. He wants man to know for a certainty concerning his eternal destination, whether heaven or hell. God furthermore wants man to have perfect clarity in distinguishing sin from righteousness. Simply put, God has no desire for believers to live in a confused state of mind. Had sin never entered into the world, there would be no conflicting feelings or voices introducing the confusion so prevalent today. Yet, God’s truth becomes even more essential in order to clear up the confusion caused by sin and Satan.
