Good theology is based in the belief that God exists, is personal, can be known, and has revealed himself. These presuppositions motivate theologians to devote themselves to a passionate pursuit of knowledge from God’s Word. Unfortunately, the word “theologian” is used almost exclusively for vocational theologians rather than for anyone earnestly devoted to knowing God. On one level everyone who thinks about God is a theologian. But a believer whose life is consumed with knowing his Lord is most certainly a theologian, and theologians are committed to truth. Loving God means loving truth. God is a God of truth; he is truth.
