Colossians 1v21-23
And you, who once were alienated and hostile in mind, doing evil deeds, he has now reconciled in his (Jesus) body of flesh by his death, in order to present you holy and blameless and above reproach before Him, if indeed you continue in the faith, stable and steadfast, not shifting from the hope of the gospel that you heard, which has been proclaimed in all creation under heaven, and of which I, Paul, became a minister.

We are made clean, we are made righteous, we are reconciled through Christ alone. But we must hold strongly to our faith in the gospel to stay there by feeding on His word spending time in His presence and getting rid of our desires and letting His will take hold of our lives.
