Why is God's existence not more obvious? Why does he seem hidden? This is commonly known as the Problem of Divine Hiddenness. In What Can be Known about God is Plain, Tyler Taber seeks to elucidate these questions from a Christian perspective. Drawing from the work of noted Christian philosopher Alvin Plantinga, Taber addresses the Problem of Divine Hiddenness with theological acumen as well as with resources from the Reformed tradition. Taber argues that the problem has an answer when these questions are analyzed in conjunction with Plantinga's epistemology and alongside certain Reformed doctrines (for instance, the doctrines of general revelation, sin's noetic effects, the internal witness of the Holy Spirit, and so forth).
