Christians believe that the ultimate truth is a divine person. “I am the way, the truth, and the life,” says Jesus Christ. “No one comes to the Father but by me” (John 14:6). Jesus, the Son of God, the creator of the heavens and earth (Genesis 1:1), is the express image (eikon) of the Father (Hebrews 1:3).
He is also the Word (logos) of God (John 1:1) as well as the wisdom (sophia) and the power (dunamis) of God (1 Corinthians 1:24). Jesus Christ is before all things (ta panta), and by him all things cohere (susesteken) (Colossians 1:17). Every human being is surrounded and penetrated by creation, as the Apostle Paul wrote:
Because that which may be known (to gnoston) of God is manifest (phaneros) in them (enautois); for God has made it evident (ephanerosen) unto them. For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; so that they are without excuse. Romans 1:18-19
This is our epistemological situation with respect to God. We either responsibly affirm or ignobly suppress God’s plainly evident existence in creation. Reason is a tool, not a court before which God may appear as a defendant.
Philosophical theology as it is practiced rejects the epistemological situation as Paul described it.
