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).
Every unsaved person will have windows of opportunities when he becomes most receptive to the gospel of Christ. The Devil works hard to keep people in darkness and will distract them by every means necessary (i.e., the death of a loved one, a crying child, a ringing phone, busyness, etc.). The salvation of a soul involves a spiritual battle that can only be won by the Lord’s intervention. There is a window of time when the lost are most receptive to the gospel, likewise suggesting only a window of opportunity for the saved to speak for Christ. This is the very reason the apostle Paul stressed the importance of the saints of God beseeching the Lord to open to them a door of utterance (Ephesians 6:19).
