Certainly! Here are two Bible verses that clearly identify God as eternal:
Old Testament:
"But you, O Lord, are a shield about me, my glory, and the lifter of my head."
Reference: Psalm 3:3
New Testament:
"Jesus Christ is the same yesterday and today and forever."
Reference: Hebrews 13:8
These verses reflect the eternal nature of God in both the Old and New Testaments.
