According to a Christian worldview, God is the foundation of all knowledge simply because God is the ultimate foundation for everything in the most general sense. God is a maximally perfect being and therefore is perfect in knowledge: God knows infallibly and comprehensively every truth that there is to know (Ps. 139:1–16; Isa. 44:6–7; Isa: 46:8–11; Heb. 4:13). Furthermore, God is the creator and sustainer of everything else, including human beings and any other creatures (e.g., angels) who have the capacity for knowledge (Gen. 1:1, 27; Heb. 1:1–3; Heb. 11:3; Rev. 4:11). In other words, our knowledge—like everything else we possess—is a gift from God, and all human knowledge is derivative of divine knowledge. As it has often been said, we have been created by God “to think God’s thoughts after him.” Although from our perspective we regularly discover “new truths” and extend our collective knowledge, human knowledge is never truly original in any absolute sense, but only reflective and reconstructive of God’s knowledge (and even then, in a very limited fashion).
Thus, we might say, the Christian worldview affirms a “revelational epistemology”: all human knowledge is ultimately dependent upon divine revelation. Put simply, we can know truth only because God has revealed truth to us—about himself, about ourselves, and about the world around us (scientific truths, historical truths, and so forth). Christian theologians have often distinguished between two basic forms of divine revelation:
