How do we know God exists outside of time?

The understanding that God exists outside of time is supported by how Scripture describes His nature. In Exodus 3:14, when God states 'I AM', it signifies that He exists in an ever-present state that does not conform to the temporal sequences of past, present, or future. This nature of God implies that He is not subject to the flow of time, which is made evident by the eternal covenant described in Hebrews 13:20-21. Thus, the eternal aspect of God denotes that He interacts with creation but is fundamentally distinct from the temporal realm.
