OK, this is going to be short and to the point. We absolutely must get it in our head that God NEVER changes. He’s never going to change, and He never changed.
Malachi 3:6 “For I [am] the LORD, I do not change; Therefore you are not consumed, O sons of Jacob.”
He did not change between the Old Testament and the New Testament.
Mainstream churches teach that, somehow, the “mean God” of the Old Testament changed into a the “loving God” of the New Testament.
Guess what? He’s always been a Loving God! He is the Embodiment of Love.
1 John 4:8 “He who does not love does not know God, for God is love.”
My whole theology and understanding of the Truth that God never changes is foundational to my faith. If I hear that ANY teaching that says my God changed, I don’t listen to it … no matter who it comes from.
When you understand that God never changes, and that His Son was the perfect representation of His Father, there is a consistency in the Word that wasn’t there before. All of a sudden, the more “complicated” doctrines are no longer subject to our opinions and biases … and things (finally) start to add up.
God is the same, His Word never changes, His commandments never change. And, as far as His Son is concerned:
Hebrews 13:8 “Jesus Christ [is] the same yesterday, today, and forever.”
Flee from any teaching that would take away from the simplicity of the Word.
