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

The good news is that no matter where we came from, or what our lives were like when Jesus saved us, He has cleansed us from all unrighteousness (1 John 1:9). Backing up the page a couple of verses to 1 Cor. 6:9 & 10, Paul instructs us that our sin, no matter what sort, rendered us unfit for Heaven. While some may look at the list and insist they were never one of those sinners, if we understand that sin begins in the heart—even if we do not act on our desires—we were all guilty.

Once again, the good news is that no matter where we came from or what manner of sin we struggled with, when we are in Christ we are cleansed. We have been and are being sanctified, meaning that the Holy Spirit is continually cleansing us and growing us in holiness. Why? Because through faith alone in Christ alone we have been justified, meaning, declared righteous by God.

That, friend, is reason to rejoice and to walk in the holiness in which we stand!

Bonus question: Which sin listed in vv.9-10 do some people insist is not sin? How can they do this in light of the clear teaching of scripture?
