It is important that we understand that God is the same today as He was yesterday and will be tomorrow, based on our idea of time - God is eternal and exists outside of the Laws of Nature that we adhere to.
Often times, we may read our Bible and feel like we are reading something of an ancient past that doesn’t exist anymore, however, it is very important that we understand that God does not change, and He is still there, the same was He was during the Biblical times we read about.
God is from all eternity:
Psalm 93:2 (NKJV): 2 Your throne is established from of old; You are from everlasting.
Earth and heaven will perish, but He remains:
Psalm 102:26-27 (NKJV): 26 They will perish, but You will [a]endure; Yes, they will all grow old like a garment; Like a cloak You will change them, And they will be changed. 27 But You are the same, And Your years will have no end.
God is the first and the last:
Isaiah 48:12 (NKJV): “Listen to Me, O Jacob, And Israel, My called: I am He, I am the First, I am also the Last.
Created things have a beginning and an end, but the Creator - not God. As a child, I recall pondering the question, “Who made God?” But the answer is simple - God did not need to be made because He was always there. He exists forever; He is always the same; He does not grow old; His life does not wax or wane; He does not gain new powers or lose old ones; He does not mature or develop, He is already perfect and full and cannot change for the worse.
The fundamental difference between us, His creation, and God is that we are mutable and our nature condones change, whereas God is immutable and will never cease to be what He is, which is perfection, as described in Hebrews 7:16 (NKJV): 16 who has come, not according to the law of a fleshly commandment, but according to the power of an endless life.
God’s character does not change as ours does. Stress and shock can alter the character of a person, but nothing can alter the character of God, which is absolute perfection. In our course of life, tastes and outlook may change radically - we may regret things we said in the past, good people can become bad, and vice-versa, and we can never see the beginning and the end at the same time like God can. He never becomes less truthful, or less loving, or less caring - He is always perfect, Holy, and just.
Exodus 3:5-7 (NKJV) is a great description of this - 5 Then He said, “Do not draw near this place. Take your sandals off your feet, for the place where you stand is holy ground.” 6 Moreover He said, “I am the God of your father—the God of Abraham, the God of Isaac, and the God of Jacob.” And Moses hid his face, for he was afraid to look upon God. 7 And the Lord said: “I have surely seen the oppression of My people who are in Egypt, and have heard their cry because of their taskmasters, for I know their sorrows.
God’s goodness and holiness show generosity towards men, and hostility towards sin:
James 1:17 (NKJV): 17 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’s truth does not change as ours may. People sometimes say things that they do not mean, perhaps because they don’t know their own mind, or simply views and opinions change. All of us sometimes have to take back words we said, or wish we didn’t say something, or eat our words because undeniable facts refute something we talked about. Whatever the case, the point is that human words are unstable, but not the Word of God.
No circumstances prompt God to have to recall His words, and no changes in His own thinking require Him to amend them at a later time:
Isaiah 40:6-8 (NKJV): The voice said, “Cry out!” And [a]he said, “What shall I cry?” “All flesh is grass, And all its loveliness is like the flower of the field. 7 The grass withers, the flower fades, Because the breath of the Lord blows upon it; Surely the people are grass. 8 The grass withers, the flower fades, But the word of our God stands forever.”
Nothing can annul God’s eternal truth - John 10:35 (NKJV): 35 If He called them gods, to whom the word of God came (and the Scripture cannot be broken)
Some may think, wait a minute, what about when He changed His mind and wiped out humanity with what we know of the story of Noah and the ark?
This was God’s reaction to sin - one thing He has shown hostility towards. God is completely perfect and Holy, and it is written that sin bothers Him very much, and He could not stand the sight of it in His creation when they were plagued with sin, the great sins that the fallen angels committed creating the Nephilim.
The Nephilim were the offspring of the "sons of God" and the "daughters of men" before the Deluge, according to Genesis 6:1–4 6 (ESV): When man began to multiply on the face of the land and daughters were born to them, 2 the sons of God saw that the daughters of man were attractive. And they took as their wives any they chose. 3 Then the Lord said, “My Spirit shall not abide in man forever, for he is flesh: his days shall be 120 years.” 4 The Nephilim were on the earth in those days, and also afterward, when the sons of God came in to the daughters of man and they bore children to them. These were the mighty men who were of old, the men of renown.
God also vowed to never do this again, showing that it grieved Him still to do this great thing and destroy His beloved creation, no matter how much they had sinned and fallen away from Him, He was sorry that He had to do this.
Genesis 6:5-7 (ESV): 5 The Lord saw that the wickedness of man was great in the earth, and that every intention of the thoughts of his heart was only evil continually. 6 And the Lord regretted that he had made man on the earth, and it grieved him to his heart. 7 So the Lord said, “I will blot out man whom I have created from the face of the land, man and animals and creeping things and birds of the heavens, for I am sorry that I have made them.”
Genesis expresses the personal nature of God very vividly: He brings animals to Adam to see what Adam will call them (Genesis 2:19); He walks about the Garden and calls out to Adam (Genesis 3:8-9); He asks people questions (Genesis 3:11-13, 4:9, and 16:8); He comes down from Heaven to see what His creation is doing (Genesis 11:5 and 18:20-33l; and He is grieved by human sin that he repents of creating them (Genesis 6:6-7).
The Bible brings home these points and teaches us that God is not merely some cosmic principle or impersonal force, but a living, Divine Person capable of thinking, feeling, action, approving of good, answering prayers, disapproving of evil and interested in His creation.
Understand that God does not change, and He deserves our full commitment and putting Him at the center of our life that He gave us. We owe Him thanks and forgiveness for every breath we take, every experience we have, every friend we meet, our spouse, our children, and everything we enjoy in life, and even the things we don’t enjoy - we still owe it all to Him and to give Him the Glory.
