In the presence of others, Paul carefully behaved himself in such a way to bring glory to God. For example, when Paul was in the presence of the believers at Thessalonica, he was gentle, “even as a nurse cherisheth her children.” He laboured “night and day” because he “would not be chargeable” to the believers. Paul conducted himself in such a godly way that he had no problem suggesting that the believers themselves were witnesses of “how holily and justly and unblameably” he had behaved among them. Paul thought his testimony was so important that he would rather personally suffer than bring any reproach or blame upon himself or the work of God.
It is very important that the saint recognize that he is blameless in Christ at this very moment in time because of Christ’s sacrifice upon the cross. Yet, the Bible warns of one’s condition when the Lord Jesus Christ returns for His own. Thankfully, the scriptures also clearly address this event. According to 1 Corinthians 1:8, the Lord Jesus Christ “shall also confirm you unto the end, that ye may be blameless in the day of our Lord Jesus Christ.” The same truth is expressed in 1 Thessalonians 3:13 when the Bible says that the Lord desires to stablish the believers’ “hearts unblameable in holiness before God . . . at the coming of our Lord Jesus Christ with all his saints.” How is this accomplished? 1 Thessalonians 5:23 offers the answer when it mentions being “preserved blameless.” This preservation is not through man’s efforts but only through the work of Christ. He preserves the Christian positionally blameless.
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.
