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.
Joy and peace! Any sensible person would readily admit his desire for a life filled with joy. Yet, few people understand the prerequisites for regularly living that way. Previous studies mentioned several of joy’s accompanying virtues, but today’s passage provides one of joy's unifying properties. According to our passage, peace accompanies joy. Proverbs 12:20 also expresses this same relationship: “Deceit is in the heart of them that imagine evil: but to the counsellors of peace is joy.” Those who seek peace will often find joy in this life because peace and joy are entwined. Isaiah 55:12 restates this truth: “For ye shall go out with joy, and be led forth with peace.” It is important to note that men will not “go out with joy” unless they are first “led forth with peace.” Peace and joy are always inseparable. Those who have the peace of God after they are at peace with God through salvation will experience "joy unspeakable" (1 Peter 1:8).
