How are we made pure according to the Bible?

The Bible explains that our purity is not achieved through our own efforts but through God's sovereign will, the atoning sacrifice of Jesus Christ, and faith. John 1:7 stresses that the blood of Jesus Christ purifies us from all sin, highlighting the sufficiency of His sacrifice. Furthermore, Scriptures like Acts 15 establish that our hearts are purified by faith, indicating that true cleansing comes when we trust in Christ alone for our righteousness. Therefore, purity is a divine work that involves God's will, Christ's redeeming blood, and our response of faith.
