4 Bible Verses about Cleansed Consciences

how much more shall the blood of Christ, Who through the Eternal Spirit offered Himself without blemish to God, cleanse your conscience from dead works to serve the living God?

let us approach with a true heart in full assurance of faith, having had our hearts sprinkled from an evil conscience, and our body washed with pure water,

which, in its anti-type, immersion, now saves you also (not a putting away of the filth of flesh, but the requirement of a good conscience toward God), through the resurrection of Jesus Christ,

If we confess our sins, He is faithful and righteous to forgive us our sins, and to cleanse us from all unrighteousness.
