Short answer is “Nope!”
A longer and far more thoughtful answer deserves a careful and reflective read. Roger Olson challenges this popular notion that God is timeless and gets the mental juices flowing. Reasons God cannot be timeless include a being who “cannot interact with temporal beings.” That would be us. If God is timeless, then he cannot respond to our prayers. In fact, a timeless God cannot be a relational God and that, my friends, means a timeless God is incapable of love! A few have proffered some kind of hybrid notion that God is timeless before creation and enters into time after creation, which is just another way of defending a timeless God. Olson (rightly, IMO) pushes back on this idea as well. I highly recommend Olson’s post to you. He writes:
Nowhere does the biblical story of God, the biblical narrative that identifies God for us, and upon which classical Christian theology claims to be based, say or even hint that God is “outside of time” or “timeless” or that all times are “simultaneously before the eyes of God.” This view of God’s eternity entered into Christian theology from Greek philosophy which regarded time as imperfection. Greek philosophy was notoriously negative with regard to time. Hebrew thought was not; it regarded time and history as the framework for God’s action.
