Both Scripture and science assert the beginning of the universe. The timeless mystery before the world’s creation is often described using the term eternity past. Speaking of “eternity past” is particularly common in theological contexts as a way to portray the eternal existence of God.

Physical life here on earth ceases, but God has revealed a never-ending human existence beyond physical death. The term eternity future refers to life beyond the present world and the continuation of an infinitely long timeline.
