'Sins' in the Bible

He personally carried our sins in His body on the cross [willingly offering Himself on it, as on an altar of sacrifice], so that we might die to sin [becoming immune from the penalty and power of sin] and live for righteousness; for by His wounds you [who believe] have been healed.

For indeed Christ died for sins once for all, the Just and Righteous for the unjust and unrighteous [the Innocent for the guilty] so that He might bring us to God, having been put to death in the flesh, but made alive in the Spirit;

Above all, have fervent and unfailing love for one another, because love covers a multitude of sins [it overlooks unkindness and unselfishly seeks the best for others].
