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.
Christians should first and foremost focus on their walk with the Lord. As such, believers are instructed to add virtue, knowledge, temperance, patience, godliness, brotherly kindness, and charity to their faith. However, notice that every believer is to be “giving all diligence” (with great effort, but without haste). Of all these graces mentioned, faith seems to be the most foundational of them all. Unfortunately, far too many believers never grow beyond faith, making them unable to put forth much diligence in adding the other graces. Believers should be growing in grace daily (like those listed above) and in the knowledge of our Lord and Saviour (2 Peter 3:18). The word of God remains the only viable source from whence this diligent growth springs forth (1 Peter 2:2).
