There is but one only living and true God, who is infinite in being and perfection, a most pure spirit, invisible, without body, parts, or passions, immutable, immense, eternal, ……..(Of God, and of the Holy Trinity -WCF Chapter II -I)
Our God is immutable. God is not capable of or susceptible to change. God alone is perfect, he cannot change for the better. He is perfectly holy, perfectly good, perfectly just, perfectly merciful, God is always perfect is every way. He is an unchangeable God. He does not change. Mal 3:6 “For I the LORD do not change;…”.
While everything else change around us, God remains the same. Everything around us can fall apart, God is still the same. When our bodies grow weak with age and sick with pain, we look to our unchanging God who has promised sufficient grace to meet our every need. There is real peace and joy that God does not change what He has promised. What a comfort that our unchanging God is on our side.
Jas 1:17 “.. the Father of lights with whom there is no variation or shadow due to change.”
“Great is Thy faithfulness, O God my Father;
There is no shadow of turning with Thee;
Thou changest not, Thy compassions, they fail not;
As Thou hast been, Thou forever will be.”
