How does God's immutability relate to His forgiveness?

God's immutability means that He does not change; this attribute guarantees that His promises, including the promise of forgiveness, remain steadfast and secure. In Malachi 3:6, God declares that He does not change, which provides comfort to His people, ensuring that His covenant of grace is unbreakable. This immutability is foundational because it assures believers that regardless of their failures or struggles, God's commitment to forgive is unchanged. Therefore, when we seek His forgiveness through Christ, we can trust that He will uphold His word and cleanse us from all unrighteousness, maintaining His faithful and just nature.
