'Conscience' in the Bible

which is a figure for the time present; according to which are offered both gifts and sacrifices that cannot, as touching the conscience, make the worshipper perfect,

how much more shall the blood of Christ, who through the eternal Spirit offered himself without blemish unto God, cleanse your conscience from dead works to serve the living God?

let us draw near with a true heart in fulness of faith, having our hearts sprinkled from an evil conscience: and having our body washed with pure water,

Pray for us: for we are persuaded that we have a good conscience, desiring to live honorably in all things.
