'Conscience' in the Bible

This was a symbol for the time then present, when gifts and sacrifices were offered that could not perfect the conscience of the worshiper.

let us draw near with a sincere heart in the assurance that faith brings, because we have had our hearts sprinkled clean from an evil conscience and our bodies washed in pure water.

Pray for us, for we are sure that we have a clear conscience and desire to conduct ourselves rightly in every respect.
