Hebrews 9:14
how much more will the blood of Christ, who through the eternal Spirit offered himself without defect to God, cleanse your conscience from dead works to serve the living God?
Paul urges a cleanse conscience that is worked out in work and rest in Hebrews 9:14—look for "god" and "how". Choose cleanse conscience in prayers we actually pray—brighten hope by remembering.
Hebrews speaks here as epistle/letter writing, developing cleanse conscience. Read in Hebrews 9, its force becomes clearer. Listen for “god” alongside “how”.
