In Psalm 90:2, we read that God is “from eternity to eternity” (me olam ad olam); it could be said that Jehovah is “from hidden time to hidden time” (Gesenius). It thus appears that the Hebrew-Aramaic scriptures (Tanakh) depict YHWH as a dynamic being within time somehow. Concerning the God of the Hebrews, we read: “temporal categories are inadequate to describe the nature of God's existence” (Zodhiates 2348). Nevertheless, olam when used of the Creator in Ps. 90:2 expresses “the idea of a continued, measurable existence, rather than a state of being independent of time considerations” (2348).
Moreover, the question regarding how a timeless deity possibly responds to prayer might lend support to the temporal view of God: “For in responding to another it is of the essence that one first acts, then waits for the other to react, then acts responsively, and so on. There seems to be no way this sequence could be collapsed, as it were, into a single timeless moment” (William Hasker in God, Time, and Knowledge, page 156).
