Knowledge of spiritual things is based upon the identity of Jesus Christ as God. Why? Because if Jesus is the Son of God, then Jesus is God. God does not err; if Jesus is God, Jesus does not err. Everything Jesus tells us can be trusted. If He tells us God is a certain kind of God, we can believe it because he is God Himself and speaks truthfully. If He tells us, as He does, that the Bible can be trusted—that it comes from God, that heaven and earth will pass away but the Word of God, being divine in nature, will never pass away—then we can trust the Bible.
