God’s eternal existence is a theme that is sounded through the entire Bible.
If one aspect of God’s eternality is true, then God exists. Since the universe and the world exist, there must have been a cause for that creation. The cause is God, plain and simple. There has never been proof of the contrary, and there is plenty of proof the cause is God.
All one has to do is view the creation, and its design will testify to the existence of God. The psalmist wrote, “The heavens declare the glory of God, and the sky above proclaims his handiwork,” (Psalm 19:1 ESV).
Since the universe had a beginning, which even atheists agree it did, and since God is the cause for that beginning, as the psalmist wrote, then God exists. There is at least one aspect of God’s eternality that is true. The conclusion, therefore, is inescapable.
The psalmist continues in the next verse, “Before the mountains were brought forth, or ever you had formed the earth and the world, from everlasting to everlasting you are God,” (Psalm 90:2 ESV). Not only was God existent before the worlds began, he will exist when the universe is no more.
God’s eternality and immutability give us great comfort. The writer of Hebrews proclaimed:
“So when God desired to show more convincingly to the heirs of the promise the unchangeable character of his purpose, he guaranteed it with an oath, so that by two unchangeable things, in which it is impossible for God to lie, we who have fled for refuge might have strong encouragement to hold fast to the hope set before us,” (Hebrews 6:17-18 ESV).
The truth of God’s promises of eternal life, since God is eternal, will be true for all eternity! God be praised for his eternal existence and the truth of his promises to us!
