There are two areas in which a man can be blameless. He can be blameless in his practice based upon his efforts to do right. Additionally, a believer can be blameless positionally, but this is completely based upon the finished work and righteousness of Christ. This second area of blamelessness is the subject of Ephesians 1:4 as is also the case in Colossians 1:22. In the context of that passage, it is clear this blamelessness comes only through the reconciliation of Christ (Colossians 1:21). This means that in Christ, believers bear no guilty responsibility for sins they have committed. Instead, believers are viewed and accepted in the righteousness of Christ (Ephesians 1:6).
Some people incorrectly conclude that someone is blameless only when he does nothing wrong, but the scripture teaches that “all have sinned, and come short of the glory of God” (Romans 3:23). The Bible continues by stating that “there is none that doeth good, no, not one” (Romans 3:12). In other words, no one ever born upon the earth, apart from the Lord Jesus Christ, has ever been sinless. This includes people like Zacharias and Elisabeth although the Bible does say that they were “blameless” concerning the commandments and ordinances of the law. How could someone be blameless and not be sinless? To be blamed suggests a failure to make wrongs right. As such, one can deduce that when Zacharias and Elisabeth sinned against the Lord, they did what the law required to make things right with God. They were blameless in the law.
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.
