How can Christians handle the struggle with sin?

The struggle with sin is a reality for every believer, as we live in bodies affected by sin while being made righteous in Christ. Understanding our identity—as elucidated in Luther's teaching—helps Christians to approach sin with humility and hope. We should recognize that our righteousness is secured in Christ, which frees us from despair over our failures. Simultaneously, we must engage in the daily battle against sin by confessing and seeking God's strength, knowing that He will transform us into His image fully when we receive new bodies (Philippians 3:21).
