23 Feb 1 Peter 2:21; 2 Corinthians 3:18
21 For you have been called for this purpose, since Christ also suffered for you, leaving you an example for you to follow in His steps,
2 Corinthians 3:18
18 But we all, with unveiled face, beholding as in a mirror the glory of the Lord, are being transformed into the same image from glory to glory, just as from the Lord, the Spirit.
The Christian has pledged to seek to become like Jesus. If we are like Jesus, we will be the kind of people who will have the most rewarding and abundant life possible. We will also be reaching out to others with the Gospel. Paul encouraged the Corinthians to, “aim for perfection”. Perfection is Jesus. Aim to live, think, and act like Jesus. Sin means “missing the mark.” To sin is to live and act in an un-Christlike way. We will sin, but keep aiming for the, “bull’s eye”. “When you sin, confess your sin to God, and you will find Him faithful and just. He will forgive you of your sins and purify you from all unrighteousness.” John said, “Dear friends, now we are children of God, and what we will be has not yet been made known. But we know that when he appears, we shall be like him, for we shall see him as he is. Everyone who has this hope in him purifies himself, just as he is pure” (1 John 3:2, 3)
When we see Christ, we will, in fact, be perfect in all ways, for we will be like Him. Until then, we are to strain to be like Him. We are to continue to aim for Christlikeness — which is purifying ourselves.
