Many people have the mistaken notion that anything factual is part of God’s truth. It logically follows, then, that the Bible does not contain all of God’s truth. That idea, however, is contradicted by what the Bible says about truth.
Jesus said of Himself, “I am the truth.” He doesn’t say He is one truth among many truths, or part of the truth, but that He is the truth. That statement alone separates God’s truth from science and from the theories of psychology.
