God is not operating in time. He is the author of time.

Time, reason, and all transcendent categories are parts of creation, they are not God’s essence, they are how He allows us to make sense of creation — and the life of Christ is how He revealed who God truly is. This is what it means to be the Alpha and the Omega, and that all things were made through Him (the incarnate Christ).

There’s a beautiful tradition here that made this explicit, but unfortunately lost in the modern west.

What did God do after his ascension?

He created the world.

This is why church fathers denied a “pre-incarnate” Christ, pointing out that the incarnate Christ is eternal and outside of time — that Moses and even Adam and Eve in the garden, Enoch, all were with Christ.

This is what John 1 makes clear.
