The existence of God cannot be proved or disproved. The Bible says that we must accept by faith the fact that God exists: “And without faith it is impossible to please God, because anyone who comes to Him must believe that He exists and that He rewards those who earnestly seek Him” (Hebrews 11:6). If God so desired, He could simply appear and prove to the whole world that He exists. But if He did that, there would be no need for faith. “Then Jesus told him, ‘Because you have seen me, you have believed; blessed are those who have not seen and yet have believed’” (John 20:29).
That does not mean, however, that there is no evidence of God’s existence. The Bible states, “The heavens declare the glory of God; the skies proclaim the work of His hands. Day after day they pour forth speech; night after night they display knowledge. There is no speech or language where their voice is not heard. Their voice goes out into all the earth, their words to the ends of the world” (Psalm 19:1-4). Looking at the stars, understanding the vastness of the universe, observing the wonders of nature, seeing the beauty of a sunset—all of these things point to a Creator God. If these were not enough, there is also evidence of God in our own hearts. Ecclesiastes 3:11 tells us, “…He has also set eternity in the hearts of men.” Deep within us is the recognition that there is something beyond this life and someone beyond this world. We can deny this knowledge intellectually, but God’s presence in us and all around us is still obvious. Despite this, the Bible warns that some will still deny God’s existence: “The fool says in his heart, ‘There is no God’” (Psalm 14:1). Since the vast majority of people throughout history, in all cultures, in all civilizations, and on all continents believe in the existence of some kind of God, there must be something (or someone) causing this belief.
In addition to the biblical arguments for God’s existence, there are logical arguments. First, there is the ontological argument. The most popular form of the ontological argument uses the concept of God to prove God’s existence. It begins with the definition of God as “a being than which no greater can be conceived.” It is then argued that to exist is greater than to not exist, and therefore the greatest conceivable being must exist. If God did not exist, then God would not be the greatest conceivable being, and that would contradict the very definition of God.
A second argument is the teleological argument. The teleological argument states that since the universe displays such an amazing design, there must have been a divine Designer. For example, if the Earth were significantly closer or farther away from the sun, it would not be capable of supporting much of the life it currently does. If the elements in our atmosphere were even a few percentage points different, nearly every living thing on earth would die.
