The one who has clean hands and a pure heart,
who does not trust in an idol
or swear by a false god. Psalm 24:4

Part of the Ten Commandments is in verse 4:

Thou shalt have no other gods before me
Thou shalt not make unto thee any graven image Exodus 20

Having clean hands and pure heart, that’s what the Work of Christ was all about. He dirtied His hands on our behalf, and purified our hearts.

Are we then sinless? Absolutely not. We have been bought and paid for by the blood of Christ. I don’t begin to understand the theological implications of that action, but I do know this:

God made him who had no sin to be sin for us, so that in him we might become the righteousness of God. 2 Corinthians 5:21

Commit that verse to memory, and it will change the way you think about sin and righteousness.
