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.
Believers should seek to be pure in every facet of life. One might consider limiting this to the places he goes or the things he hears and sees, but purity demands a much greater focus. Believers ought to think on pure things (Philippians 4:8) with pure minds (2 Peter 3:1) and pure consciences (1 Timothy 3:9; 2 Timothy 1:3). In particular, believers should have pure hearts before the Lord (1 Timothy 1:5; 2 Timothy 2:22). A pure heart will lead to a pure conscience and a pure mind. A pure heart changes where a man goes, what he looks upon, and the things he allows to enter into his ears. Every Christian should strive to make sure that all things are pure.
