Christians believe God can be known. If we want to know what God is like, we aren’t left to seek mountain-top or chemically-induced experiences, wonderful as they may be. We don’t need to take a course in analytic philosophy, as intellectually satisfying as that could be.
We just behold Christ, and thus we know God.
Without this revelation, God will be misunderstood. Greatly.
Creation points us to a creator of some kind. But if all we use to know God is our experience, we’ll have a distorted, incomplete, and warped view of God.
What we experience as his sustaining of creation could be mistaken for Spinozan Pantheism
What we experience as his patient non-interference could mistakenly be taken to buttress rationalist Deism
What we experience as his dramatic occasional miracles could convince you that he is an Interventionist Butler. God On Demand.
Scripture weaves all these things together in a kind of theological God Temple. Omnipresence, Omniscience, Omnipotence (see Ps 139, the first 18 verses). And then it rips down that temple and re-builds it around the person of Crucified and risen Christ (see Colossians 1 or Hebrews 1).
Or as Luther said, Crux Sola Est Nostra Theologia
The Cross is our only Theology.
