. . . that we should be holy and without blame before Him in love (Ephesians 1:4).
In the grand purpose of our selection into Gods family, two key words are used:
Holy (Greek, hagios) stresses dedication. A holy man or woman is distinctively Gods, set apart for Gods use; separated from the secular, and consecrated to Gods service. All who are chosen are chosen to be holy.
The Colossian Christians were told to mortify the physical appetites, to put off their sinful mental attitudes and habits, and to put on the new man . . . as the elect of God, holy and beloved (Colossians 3:512). The focus is character.
Without blame refers to our reputations. This character will only be fully realized in heaven (I Corinthians 1:8), but there is a present responsibility to present your bodies a living sacrifice. . . . And be not conformed to this world: but be ye transformed by the renewing of your mind . . . (Romans 12:1,2).
The character of holiness will become the cause of a lifestyle of blamelessness. We are to be the sons of God, without rebuke, in the midst of a crooked and perverse nation, among whom ye shine as lights in the world (Philippians 2:15).
What a magnificent thought! The purpose for which we have been chosen, predestined, redeemed, and forgiven is to be holy in character and blameless in reputation, so that when God gathers us all together in Christ, we will be the praise of the glorious grace of God! HMM III
