God does not change. This immutability is in keeping with all of His attributes because in order to change, He would have to change from better to worse, from worse to better, or from one king of being to another kind of being. Daniel 9:7 says that, unlike us, God is righteous. Deuteronomy 32:4 says, “All His ways are justice, a God of truth and without injustice; righteous and upright is He.” God is perfect and infinite righteousness, so He cannot change. All that He ever was, He still is, and eternally will be.
God’s immutability should be a comfort to the believer as we go through life. Malachi 3:6 says, “I am the Lord, I do not change; therefore you are not consumed, O sons of Jacob.” God here proclaims that Israel could take comfort in God’s unchanging gracious covenant. We today can take comfort and confidence in the truth that His covenant loyalty and love do not wane when we struggle and fail. He does not change. James 1:17 says, “Every good gift and every perfect gift is from above, and comes down from the Father of lights, with whom there is no variation or shadow of turning.” God always acts in loyal, loving grace toward His children. That is how we can proclaim the promise of Romans 8:28. “We know that all things work together for good to those who love God, to those who are the called according to His purpose.”
We also must realize that God does not change with every wind of change in societal opinion. In Hebrews 13:7-9, Christians are instructed to be thankful and mindful of faithful preachers and teachers of the Word of God. Christians are also instructed there to be established in grace (that which faithful preachers and teachers proclaim) instead of being blown this way and that way by weak and false teaching. Churches that set out to be “relevant” to the age will always compromise God’s truth. Hebrews 13:8 reminds us that “Jesus Christ is the same yesterday, today, and forever.”
