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.
Too many people have assumed that believers may freely rebuke in their own authority, but there exists no scriptural basis for this. The LORD gave us an excellent example when He said, “The LORD rebuke thee, O Satan.” When rebuking the Devil, the LORD emphasized the importance of authority. No believer should ever rebuke except according to the God-given authority of scripture. In Zechariah 3:2, the LORD was His own authority, but believers do not have any such authority in themselves apart from the Lord and His word. Paul spoke expressly about this when he charged Titus to “speak, exhort, and rebuke with all authority” (Titus 2:15). It is not sufficient to flippantly invoke the Lord’s name; one must base any rebuke upon the scripture. Henceforth, it is the Lord that rebukes, never the believer.
