What is God is Forever or Ever Living means in your dictionary?

God is the Almighty Creator and Sustainer of the universe. God is endless and will never disappear for God is eternal.

“God is the Creator of everything. He is the guardian over everything. Unto Him belong the keys of the heavens and the earth…” (Quran 39:62-63)

I just look and in my dictionary it does not go past God - non existent

God is a spirit person. He lives in God's kingdom in the spirit realm. Spirit realm is different from the physical realm that we live in. Jesus taught us that those of us who earn our entry to God's kingdom will be reborn as spirit persons in God's kingdom when we die. There is no decay or death in the spirit realm. The citizens of God's kingdom live for ever participating in the activities of God's kingdom.

All it means is that the human imagination is massive and therefore this fake god is equally massive and fake.
