It has been said that an individual is not truly ready to live for the Lord until he is willing and ready to die for Him. As a believer, one should not fear death.
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).
