You are cleansed and pruned already, because of the word which I have given you [the teachings I have discussed with you]. John 15:3 (AMPC)
Everything God wants you to be or do is possible and accomplished through His Word.
He brought you into existence through His Word. James1:18.
He saved you through His Word.-See 1Corinthians 15:1, 2.
So God cleanses us with His Word.
He removes all uncleanness of sin from us with his Word. Ephesians 5:25-26 (NLT)…just as Christ loved the church. He gave up his life for her to make her holy and clean, washed by the cleansing of God’s word.
He removes from us all uncleanness of sickness and destruction with His Word. Psalms 107:20 (CEV) By the power of his own word, he healed you and saved you from destruction.
The more you yield yourself to what God says to and about you in His Word the more you’re cleansed or renewed and thus transformed, making you fit and usable for God’s purposes.
