Why is God's unchanging nature important for Christians?

Malachi 3:6 states, 'For I am the Lord; I change not.' This unchanging nature of God is crucial as it undergirds the beliefs surrounding His promises and character. For believers, understanding that God does not change means that His love, grace, and the covenant made with His people remain constant through all generations. This truth brings solace and security in an ever-changing world, reinforcing the idea that those whom God has chosen and called will not be consumed or abandoned. It instills confidence in the believer that their salvation, initiated by God, is secure because it is based on His immutable character.
