Why is the sanctification of the Church important?

Sanctification refers to the process by which Christ purifies and sets apart His Church for Himself. Ephesians 5:26 illustrates this by indicating that Christ loved the Church so much that He sanctified and cleansed it with the washing of water by the Word. This act of sanctification is vital for the Church as it calls believers out of the sinful practices and influences of the world and establishes them in a new identity as children of God. It emphasizes the necessity of being washed clean from sin, affirming that no one can stand before God without the cleansing work of Christ. As the Church is sanctified, it grows in holiness and reflects the character of Christ, showcasing the transformative power present within the covenant relationship.
