It's interesting how often Christians self-identify with the phrase, "I'm just a sinner saved by grace." In that estimate, sin is usually voiced with a present-tensed quality - as if sin is still the highest marker of the individual.
Yet consider Paul's language in Ephesians 1: "For consider what he has done — before the foundation of the world he chose us to become, in Christ, his holy and blameless children living within his constant care."
Our "holy and blameless"-ness has been imputed to us by the Holy and Blameless One Himself; the transfer came at the cost of His life, His blood. He now lives in us to make that "holy and blameless" Way available to us by translating Himself right through our daily life.
May we, today, not self-define according to the former condition of sin; may the Holy Spirit be our spirit and the "mind of Christ" our mind. We must begin to grasp that the truest thing about our present life is what He's already accomplished eternally for us, in us, and, so gloriously, for the sake of the lost world, through us!
