What does the Bible say about God's self-existence?

The concept of God's self-existence emphasizes that God exists independently and eternally. In John 8:58, when Jesus proclaims 'Before Abraham was, I am,' He identifies Himself with the divine name that God revealed to Moses at the burning bush. This name, commonly understood as Yahweh, signifies that God is not dependent on anything or anyone for His existence. He is the uncreated, eternal being whose essence and existence are one and the same. This declaration counters human inclination to fashion gods from our imagination or needs, affirming that the God of Scripture is wholly other and sovereign.
