When we talk about some attribute of God, we cannot exclude others because it is impossible for God to use one attribute to "exclude" others.
We learn from the Bible that God is immutable, so when we say that we cannot exclude the attributes of God such as eternity, omnipotence, omniscience, etc.
God is a Spirit and therefore can be eternally the same and that is why God is unchangeable in his being essentially in his attributes in his standards and principles, God does not change his plan, He does not grow old and His absolutes are unchangeable, He does not change His opinion or decisions as people depending on the situation they are in because He rules situations and what He said long ago in the past is valid today and will be valid in the future, He was the same, is the same and will be the same in the future.
"For I [am] the Lord, I change not;..."
Mal.3:6
The Bible contains many of God's promises that were fulfilled because God said so, and the immutability of God means that everything will be as promised because God is not a man to lie or change his mind.
"The Lord of hosts hath sworn, saying, Surely as I have thought, so shall it come to pass; and as I have purposed, [so] shall it stand:
Isa.14:24
Here are some examples:
Flood:
,,And the Lord said, My spirit shall not always strive with man, for that he also [is] flesh: yet his days shall be an hundred and twenty years.”
Gen. 6:3
Abraham's descendants:
"And I will make of thee a great nation, and I will bless thee, and make thy name great; and thou shalt be a blessing:”
Gen. 12:2
Scattering Jews around the world:
"And the Lord shall scatter thee among all people, from the one end of the earth even unto the other; and there thou shalt serve other gods, which neither thou nor thy fathers have known, [even] wood and stone.”
Deuteronomy 28:64
Gathering Jews, Israel became a state again after many years in 1948
"And it shall come to pass, when all these things are come upon thee, the blessing and the curse, which I have set before thee, and thou shalt call [them] to mind among all the nations, whither the Lord thy God hath driven thee, And shalt return unto the Lord thy God, and shalt obey his voice according to all that I command thee this day, thou and thy children, with all thine heart, and with all thy soul; That then the Lord thy God will turn thy captivity, and have compassion upon thee, and will return and gather thee from all the nations, whither the Lord thy God hath scattered thee. If [any] of thine be driven out unto the outmost [parts] of heaven, from thence will the Lord thy God gather thee, and from thence will he fetch thee: And the Lord thy God will bring thee into the land which thy fathers possessed, and thou shalt possess it; and he will do thee good, and multiply thee above thy fathers."
Deuteronomy 30:1-5
Here are some promises for the future.
Big trouble:
"And after threescore and two weeks shall Messiah be cut off, but not for himself: and the people of the prince that shall come shall destroy the city and the sanctuary; and the end thereof [shall be] with a flood, and unto the end of the war desolations are determined.”
Dan.9:26
"For then shall be great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be."
Matthew 24:21
Revelation from 6 to 18 heads
Eternal communion with God:
"He will swallow up death in victory; and the Lord God will wipe away tears from off all faces; and the rebuke of his people shall he take away from off all the earth: for the Lord hath spoken [it]. And it shall be said in that day, Lo, this [is] our God; we have waited for him, and he will save us: this [is] the Lord; we have waited for him, we will be glad and rejoice in his salvation."
Isa.25: 8-9
"And I heard a great voice out of heaven saying, Behold, the tabernacle of God [is] with men, and he will dwell with them, and they shall be his people, and God himself shall be with them, [and be] their God. And God shall wipe away all tears from their eyes; and there shall be no more death, neither sorrow, nor crying, neither shall there be any more pain: for the former things are passed away."
Rev.21:3 -4
And we can say that this is the essence of God "immutability" because we have seen several examples that God has fulfilled his promises and then there is no doubt that God will fulfill what he said in the future, although we do not know much about the essence of God. the essence remained the same when the Lord Jesus was the creator of everything and when he was a baby, but when he died on the cross. The Lord is always, in essence, the God who is life and who has the keys to death and hell.
,,Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me."
John 14:6
,,I [am] he that liveth, and was dead; and, behold, I am alive for evermore, Amen; and have the keys of hell and of death."
Rev.1:18
In Psalm 102, the psalmist in a way compares man and God and concludes that we are like grass that dries up, in other words we, like our material goods, are subject to change, decay and decay, and that God is eternal and unchangeable.
" My days are like a shadow that declineth; and I am withered like grass. But thou, O Lord, shalt endure for ever; and thy remembrance unto all generations.."
Ps.102:11-12
,, I said, O my God, take me not away in the midst of my days: thy years are throughout all generations. Of old hast thou laid the foundation of the earth: and the heavens are the work of thy hands.
They shall perish, but thou shalt endure: yea, all of them shall wax old like a garment; as a vesture shalt thou change them, and they shall be changed:
But thou art the same, and thy years shall have no end.
Ps.102:24-27
Regardless of the fact that we are compared to grass that can disappear very quickly, God has shown and shows us great love and mercy even so much that he died on the cross because of our disobedience and apostasy. He showed and still shows incredible love and kindness to bring us to Himself in order for us to live, and that is why, as an unchangeable God, many, many years ago, He could say:
,,The Lord hath appeared of old unto me, [saying], Yea, I have loved thee with an everlasting love: therefore with lovingkindness have I drawn thee.”
Jer.31:3
And we have a "sure rock" that we can trust forever because it is the recommendation of an unchangeable God who tells us more reasons why we should trust Him,
"Trust ye in the Lord for ever: for in the Lord Jehovan [is] everlasting strength:”
Isa.26:4
" His work is honourable and glorious: and his righteousness endureth for ever.”
Ps.111:3 ,,
"If the mountains move and waver, my mercy will not depart from you, and my covenant of peace will not waver, says the Lord, who is merciful to you."
Isa.54:10
“For the Lord is good; his mercy is everlasting; and his truth endureth to all generations."
Ps.100:5
"God [is] not a man, that he should lie; neither the son of man, that he should repent: hath he said, and shall he not do [it]? or hath he spoken, and shall he not make it good?"
· Numbers 23:19
And besides this, God also says that His word is unchangeable
,,For ever, o Lord, thy word is settled in heaven.”
Ps.119:89
and further
"All scripture [is] given by inspiration of God, and [is] profitable for doctrine, for reproof, for correction, for instruction in righteousness:
2 Tim.3:16
and we received all this as a gift and here is what is written about the gift and the Giver:
"Every good gift and every perfect gift is from above, and cometh down from the Father of lights, with whom is no variableness, neither shadow of turning.”
James 1:17
God has given us everything as a gift, but we must also mention very important warnings that God has given us in love and which are unchangeable, regardless of the fact that some of them refer to future events because God is unchangeable, so he warned us in advance.
"He that believeth and is baptized shall be saved; but he that believeth not shall be damned.. "
Mk.16:16
"And whosoever was not found written in the book of life was cast into the lake of fire.”
Rev. 20:15
Finally, let us mention that God said in advance in which group of people we should not and should not be, because there is a place for them and a terrible punishment that has been prepared and it is called "Lake of Fire".
"But the fearful, and unbelieving, and the abominable, and murderers, and whoremongers, and sorcerers, and idolaters, and all liars, shall have their part in the lake which burneth with fire and brimstone: which is the second death."
Rev.21:8
This will be:
" For I [am] the Lord, I change not;..."
Mal.3:6
