What does the Bible say about being clean through the Word?

In John 15:3, Jesus states, 'Now ye are clean through the word which I have spoken unto you,' emphasizing that it is through His teachings and the Word of God that believers find cleansing and sanctification. This concept is deeply rooted in the covenantal relationship between God and His people, which is further illustrated through teachings found in Leviticus, where the Lord instructs His people on holiness and cleanliness. The Word serves as a purifying force, guiding believers in their spiritual journey and reinforcing their identity in Christ.
