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.
As recorded in Zechariah, the people of God came to the Lord desiring to know if they should continue weeping and fasting as they had done for many years. In response, the Lord asked the people if they ever really fasted UNTO Him. In other words, were they fasting for simply prideful reasons, to be seen of men, or really fasting unto the Lord? The motive of fasting is also addressed in Matthew chapter 6. Christians should never fast in order to please men or to draw praise and attention to themselves. Fasting should be a private matter between the believer and the Lord. The benefits gained by fasting are lost when the motives are improper or impure. Those behaving hypocritically will ensure that people know they are fasting, desiring the praise of men; whereas, the truly humble seek only to please the Lord.
