What does the Bible say about the everlasting God?

In Genesis 21:33, Abraham refers to God as the 'everlasting God,' marking a profound acknowledgment of God's eternal existence. The sermon highlights that God is self-existent, never having begun to be, and always having been. He is described as the one who inhabits eternity, with no beginning or end. This essence of God being everlasting is foundational for understanding His sovereignty and the nature of His covenant with humanity. Furthermore, throughout Scripture, this eternal characteristic of God underscores that all that He does is not bound by time or human limitations.
