“The fool has said in his heart, ‘There is no God.’ They are corrupt, they have done abominable works, there is none who does good.”
— Psalm 14:1
Do you get into conversations with people who don’t believe in God? If so, then you’ve probably encountered one or two people who give no credence to your own personal experience or to the truth of Scripture. These people want hard and fast proof that God exists.
Such proof does exist. Let me give you a few bits of information I use when people want proof of God’s existence. First of all, I ask these people to consider the universe. (This is called the cosmological argument. Cosmology means “the study of the universe.”) I point out that the universe is the biggest thing there is, and it had to come from somewhere (every effect has a cause). The universe could not have created itself, because according to the First Law of Thermodynamics, you cannot create nothing out of nothing. Therefore, Someone eternal must have created it. And those are the Bible’s first words: “In the beginning God.” The second proof is the presence of life itself. Life could not have come from non-life, nor could it have happened by chance. It also had to be created. Who else could have created it but God, who is life? The third proof comes from examining the intricate design of the universe. (This is called the teleological argument. “Teleo” means “end” or “design.”) Because the universe is so intricately designed, Someone all-knowing must have designed it. The fourth proof is God’s loving care. If the earth orbited ten percent closer to the sun, we would burn up. If it orbited ten percent farther away, we would freeze and die. Instead, the earth orbits around the sun at just the right distance to sustain life. The fifth proof is the soul’s transformation. This happens so mysteriously that no one can explain it. We know only that Someone changed Paul from a killer of Christians into the world’s greatest missionary, and this Someone has changed our hearts as well.
God is the One who touches people’s lives and brings them into fellowship with Him. But He can use you to accomplish that purpose. So as you speak with those who challenge God’s existence, ask Him to show you when to present any or all of the information I’ve shared with you. And pray that God will ultimately reveal Himself to them.
