How do we know the importance of washing in the Word of God?

The significance of being 'washed' by the Word lies in its role in maintaining our communion with God. While our standing before God in Christ is perfect, our daily walk often leads us to become defiled. The act of truly engaging with the Word helps identify these defilements, as it reflects our spiritual state and offers cleansing. John 15:3 illustrates this need for continual cleansing through Christ’s words, emphasizing that a believer must consistently come back to the Word for refreshment and purification, enabling us to offer spiritual sacrifices pleasing to God.
