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.
Unity only comes from and through the Lord Jesus Christ, but once it comes, the saints of God must endeavour to keep that unity. One of the reasons why people find unity so elusive is because it requires sacrifice from all those who would enjoy its benefits. Only saints who exercise “lowliness and meekness, with longsuffering” will experience unity. No two believers who are using the minds that God gave them will believe every minute detail alike, yet they can enjoy sweet unity and fellowship in the Lord. Obviously, there are times and reasons for believers to divide, but there are also times for believers to forbear “one another in love” and endeavour to keep the unity. This unity works by love and can only be bonded through peace.
