The dynamic theory of time (A-theory) holds that God is not timeless and relates to the actual world within the bounds of time. First advocated by J. M. E. McTaggart, this entails a tensed knowledge of God and that all events are not simultaneously real, there is only one absolute now. Given that the General Theory of Relativity is true, objects in motion tend to slow down. This in no way takes away from an absolute now; Lorentz advocates that this absolute now cannot be measured because measuring devices are in motion. God’s relationship to time would be the absolute now. Dynamic theory holds that façon de parler (in a manner of speaking), prior to creation (cf. Jude 25); God was timeless and so entered time to relate to man.
The static theory of time (B-theory) holds that God is omnitemporal and continues to exist timelessly (atemporal) since creation. There are no tensed facts. Yesterday is just as real as today, which is just as real as the year 2039. God is simple under a view of timelessness. If God is simple then He cannot be temporal, for a temporal being is related to the various times at which it exists: It exists at t1 and at t2, for example. But a simple being stands in no relations.
