There's a well known passage at the end of Isaiah chapter 40. It's often quoted to those who are feeling weak or tired because it speaks of a God who never grows weak or weary, a God who is able to renew our strength so that we feel again that we could soar like eagles.
That passage begins in verse 28 with the questions, "Have you not known, have you not heard that the Lord is the everlasting God, the Creator of all the earth?" El Olam - the eternal or everlasting God. Isaiah wasn't presenting a new idea here. Already in Genesis 21 we saw Abraham calling on the name of Yahweh El Olam.
God is not only the Ancient of Days; He is El Olam, the God who will be there forever. As the New Testament writer to the Hebrews wrote, He is, "yesterday, today and forever the same." (Heb 13: 8) We don't need to worry that He will break His promises or fail to hold up His end of a covenant. Unlike ministries or churches that change focus during a leadership transition, unlike businesses that fail under a new managing director, God's promises and covenants are forever. Our salvation is eternally secured. Hebrews 9: 15 says that we have an eternal inheritance.
Small children, on learning that God made the world, sometimes ask, "But who made God?" And of course the answer is that no one did; God has always existed and he always will.
In the first two verses of Psalm 90, Moses declares that God has been our dwelling place, our home, through all generations. (It was a big comfort to me during the two years that I was homeless.) He goes on to proclaim, "From everlasting to everlasting (olam ad olam) You are God."
There's great security in knowing that we serve El Olam, the eternal God whose kingdom is also everlasting.
