1 Corinthians 6:11

And such were some of you. But you were washed, you were sanctified, you were justified in the name of the Lord Jesus Christ and by the Spirit of our God.
(1 Corinthians 6:11)

Three points:

1. Some of you

All of us have broken God's laws. Isaiah says that "all our righteousnesses are like filthy rags" (Isaiah 64:6). The absolute best we do is not good enough.

2. Washed, Sanctified, and Justified

Washed means fully washed, totally clean, no spots, no stains, so fully that it is like brand new.

Sanctified means made holy, that is, fit to be used by God. A king would not use bent, beat-up, dirty plates and cups; he would use the best, the most perfect and clean. This is how God views those who have repented, confessed our sins, and have faith in Jesus Christ alone for forgiveness.

Justified means considered innocent. We are not innocent, but after faith God considers us to be fully, completely, wholly innocent; it is as if we never sinned or broken God's laws.

3. Lord Jesus Christ

We cannot do this, a psychiatrist cannot, a surgeon cannot, no one can--only God. The Lord Jesus suffered for out sins; He is the perfect sacrifice. The Holy Spirit opened our eyes to our condition and moved us to repentance.

Rejoice! Our sins are forgiven so completely that there is no reason to think of them again. That is easier said then done, but we can remind ourselves and believe that it is finished.
