I would agree with @cwhenderson in saying that Egnor here is not referring to special instances (which people sometimes call theophanies) of God’s presence such as Moses and the burning bush, a hand writing on the wall, or the most perfect instance, Jesus Christ, the Word who became flesh. That being said, although we do affirm that God is transcendent over creation, we also affirm that he is immanent: God continually sustains all things in existence (Heb. 1:1-3, Col. 1:15-20), God is providentially involved in all things (e.g. Romans 8:28) and you can’t hide from God by going to some physical place. That doesn’t mean that we can sense God with our physical sense, but I actually can agree with Egnor that reason, properly used, should be able to “sense” God. In other words, I believe in natural theology: it is possible to deduce the existence and some attributes of God using only reason (though just to be clear, not science alone - that could be one area where my views and Egnor’s as an ID advocate differ).
