What does the Bible say about the immortality of God?

In Scripture, it is clearly indicated that God is the sole possessor of immortality, as seen in 1 Timothy 6:16, which declares that He alone has immortality and dwells in unapproachable light. In contrast, humans are not immortal; we are created from dust and will return to it (Genesis 3:19). This fundamental distinction emphasizes the holiness and eternal nature of God in comparison to our fleeting existence. God is eternal from everlasting to everlasting, while humanity is bound by time and subject to decay and death.
