The word “theology” comes from two Greek words that combined mean “the study of God.” Christian theology is simply an attempt to understand God as He is revealed in the Bible. No theology will ever fully explain God and His ways because God is infinitely and eternally higher than we are. Therefore, any attempt to describe Him will fall short (Romans 11:33-36). However, God does want us to know Him insofar as we are able, and theology is the art and science of knowing what we can know and understand about God in an organized and understandable manner. Some people try to avoid theology because they believe it is divisive. Properly understood, though, theology is uniting. Proper, biblical theology is a good thing; it is the teaching of God's Word (2 Timothy 3:16-17).
The study of theology, then, is nothing more than digging into God’s Word to discover what He has revealed about Himself. When we do this, we come to know Him as Creator of all things, Sustainer of all things, and Judge of all things. He is the Alpha and Omega, the beginning and end of all things. When Moses asked who was sending him to Pharaoh, God replied “I AM WHO I AM” (Exodus 3:14). The name I AM indicates personality. God has a name, even as He has given names to others. The name I AM stands for a free, purposeful, self-sufficient personality. God is not an ethereal force or a cosmic energy. He is the almighty, self-existing, self-determining Being with a mind and a will—the “personal” God who has revealed Himself to humanity through His Word, and through His Son, Jesus Christ.
To study theology is to get to know God in order that we may glorify Him through our love and obedience. Notice the progression here: we must get to know Him before we can love Him, and we must love Him before we can desire to obey Him. As a byproduct, our lives are immeasurably enriched by the comfort and hope He imparts to those who know, love, and obey Him. Poor theology and a superficial, inaccurate understanding of God will only make our lives worse instead of bringing the comfort and hope we long for. Knowing about God is crucially important. We are cruel to ourselves if we try to live in this world without knowing about God. The world is a painful place, and life in it is disappointing and unpleasant. Reject theology and you doom yourself to life with no sense of direction. Without theology, we waste our lives and lose our souls.
All Christians should be consumed with theology—the intense, personal study of God—in order to know, love, and obey the One with whom we will joyfully spend eternity.
