That God is unchangeable is foundational to the character of God. Because He is unchangeable, all His attributes are intact throughout all time. He will never lose any part of His nature. Each trait is present in every circumstance. For instance, in the midst of man’s great wickedness, God exercises justice and righteousness because God is holy. As He executes justice and righteousness, God remains love. “Remains” is the proper word to use here because God is love. He is not just loving, He is love. He is the very essence of love.
God is complete.
Exodus 3:14 says, “God said to Moses, “I AM WHO I AM”; and He said, “Thus you shall say to the sons of Israel, ‘I AM has sent me to you.'” Hebrews 13:8 says, “Jesus Christ is the same yesterday and today and forever.”
These verses tell us that God is complete. He doesn’t need further growth or improvement. He doesn’t need more expertise. He has already attained. He has already reached the finality of who He is. He is all-perfect and all-mature. He is capable of being God.
God is consistent.
In Malachi 3:6 God declares, “For I am the Lord, I change not; therefore ye sons of Jacob are not consumed.” In Lamentations 3: 22,23 Scriptures say, “Because of the Lord’s great love we are not consumed, for his compassions never fail. They are new every morning; great is your faithfulness.”
These verses tell us that God is never swayed into being somebody else. He remains who He is regardless of how we are before Him. He acts and behaves according to His nature and never in accordance with how favorable or unfavorable we look before Him. He gives blessing upon blessing not because man is good but because HE always is.
God is reliable.
Numbers 23:19 says, “God is not human, that he should lie, not a human being, that he should change his mind. Does he speak and then not act? Does he promise and not fulfill?”
This verse tells us that God doesn’t speak thoughtlessly or on a whim. He is never impulsive. Backed by an eternity of experience and knowledge, all He speaks is certain and trustworthy. I can count on Him to make good on all that He says.
A popular quote says, “Change is the only constant thing in this world.” However, there’s an equally popular quote that says, “Some things never change.” These are conflicting statements, right? Because the only constant thing in this world is not a thing. It’s a person and it’s God.
Let’s look at Psalm 102 for a moment and see how it ends beautifully. It says these about our unchangeable God:
“In the beginning you laid the foundations of the earth,
and the heavens are the work of your hands.
They will perish, but you remain;
they will all wear out like a garment.
Like clothing you will change them and they will be discarded.
But you remain the same, and your years will never end.
God is constant. Best of all, He is our constant companion. He will never change and He will never leave.
