What does the Bible say about cleansing from sin?

The cleansing from sin is a profound theme in Scripture, highlighted by the atoning work of Jesus Christ. In 1 John 1:7, it is expressed that 'the blood of Jesus Christ his Son cleanses us from all sin,' emphasizing the completeness and sufficiency of Christ's sacrifice. This cleansing is not dependent upon our efforts but is a divine provision, as reflected in Hebrews 9:13-14, which illustrates how the blood of Christ purges our conscience from dead works. This transaction allows believers to serve the living God with purity and assurance of forgiveness.
