The eternity of God relates to time. God is not limited by or bound to time. Time as we know it is a succession of events and it is this that God is above.
To God all things are equally and always present, there is no distinction between past, present and future. God exists endlessly – (endlessly backwards and forwards in what we would call time.) Think of it this way, God’s eternity extends to past infinity and to future infinity. This is why Psalm 90 can say ” from everlasting to everlasting you are God.”
Take note – The above definition is not to suggest that time is unreal to God or that it does not exist. While God sees everything as an eternal now in relation to man and creation He does see a succession of events in time. God created time, but He is not in time.
Wayne Grudem in his Systematic Theology (p. 168) states “God has no beginning, end or succession of moments in His own being, and he sees all time equally and vividly, yet God sees events in time and acts in time.”
The good news from this is we can have confidence because God has never, nor will He ever cease to exist. His sustaining, providential control of all things and events is assured.
