As a creature whose existence is predicated on time, it is a strenuous challenge to thoroughly ponder upon the timelessness of God. Moses writes: “Before the mountains were brought forth, or ever You had formed the earth and the world, even from everlasting to everlasting, You are God” (Psalm 90:2). Prior to the creation of time, space, and matter in Genesis 1:1 there was the everlasting, eternal God. When Jesus returns and eliminates time, space, and matter there will be the everlasting, eternal God.
For creatures whose existence is predicated on time decades, centuries, and millennia are vast swatches of human existence. For the One who is from everlasting to everlasting, a thousand years “are like yesterday when it is past, and like a watch in the night” (i.e. three hours) (Psalm 90:4).
For creatures whose “days of our lives are seventy years, and if by reason of strength they are eighty years” (Psalm 90:10), it is the epitome of wisdom to “number our days (i.e. make every day count) that we may gain a heart of wisdom” (Psalm 90:12).
Like His incorruptible word which lives and abides forever (1 Peter 1:23), Jehovah isn’t going anywhere. Ever.
He is the Everlasting to Everlasting God.
