In the body of his flesh through death, to present you holy and unblameable and unreproveable in his sight: In the body of his flesh - By Christ's assumption of a human body, and dying for man, he has made an atonement for sin, through which men become reconciled to God and to each other.
To present you holy - Having saved you from your sins.
Unblamable - Having filled you with his Spirit, and written his law in your hearts, so that his love, shed abroad in your hearts, becomes the principle and motive to every action. The tree therefore being good, the fruit is also good.
And unreprovable - For, being filled with love, joy, peace, meekness, gentleness, and goodness, against these there is no law; and as they were called to love God with all their heart, soul, mind, and strength, and their neighbor as themselves, the whole spirit and design of the law was fulfilled in them, for love is the fulfilling of the law.
In his sight - At the day of judgment. None can enjoy heaven who have not been reconciled to God here, and shown forth the fruits of that reconciliation in being made holy and unblamable, that, when they come to be judged, they may be found unreprovable.
