Hebrews 9:14; Hebrews 10:2; Hebrews 10:22; Hebrews 13:18

14 How much more shall the blood of Christ, who through the eternal Spirit offered himself without spot to God, purge your conscience from dead works to serve the living God?
2 For then would they not have ceased to be offered ? because that the worshippers once purged should have had no more conscience of sins.
22 Let us draw near with a true heart in full assurance of faith, having our hearts sprinkled from an evil conscience, and our bodies washed with pure water.
18 Pray for us: for we trust we have a good conscience, in all things willing to live honestly.
