My friend Caleb made a comment to me the other day that I thought I'd pass on:
Romans 8:13 says we're to put to death the deeds of the body. Colossians 3:5 says we're to put to death our "members which are upon the earth". There's one sure way to put to death what comes from the first Adam: looking at the face of God (Exodus 33:20). If we want to put to death our members on the earth, we need to look at Christ (2 Corinthians 3:18). As we behold the glory of God in the face of Jesus Christ, death works in us.
Frankly, I need to be reminded of that.
