I am teaching through 1 Peter on Wednesday nights and Colossians on Sunday mornings. In the providence of God I covered 1 Peter 1:17-19 and Colossians 1:21-23 the same week. These two passages came together to remind me of God's incomprehensible grace.
1 Peter 1:19 describes Christ as a lamb "unblemished," of course in reference to his perfect and sinless life. Then in Colossians 1:22 it says, "yet he has now reconciled you in His fleshly body through death, in order to present you before Him holy and blameless and beyond reproach."
What jumped out at me as I studied and prepared these two passages was that the word that is used to describe Christ, "unblemished," is the exact same word, in the Greek, that is used to describe how Christ will present us. We will be holy, unblemished, by the grace of God. He will take that which He cannot look upon and, through Christ, make us that which He loves to look upon.
"He made Him who knew no sin to be sin on our behalf that we might become the righteousness of God in Him." - 2 Corinthians 5:21
