Can you prove the existence of God? I admire people who take their religion seriously (especially when they try to help others and live a good life). But I can't have their faith in God or believe in something I can't prove. — K.G.Y.

Have you ever asked yourself how many times you act on faith every day? The truth is, we live by faith all the time, and without faith it would be impossible to live. Let me explain.

For example, right now you are probably sitting in a chair as you read this newspaper. But did you inspect the chair before you sat down, or did you first send it away to a laboratory to be tested? No, of course not. You believed it would hold you, probably because it's done so many times before, and you've seen it hold other people also. And yet you acted by faith when you sat in the chair. At the same time, it wasn't unreasonable for you to do so.

Faith in God is something like this. Faith in God isn't blind or unreasonable, because God has left His "footprints" all around us. As the Bible says, "Since the creation of the world God's invisible qualities—his eternal power and divine nature—have been clearly seen, being understood from what has been made" (Romans 1:20). It's far more reasonable to believe in God than to believe this incredibly intricate universe just happened.

But the most compelling evidence for God is this: He became a man! That man was Jesus, who was God in human flesh. Do you want to know what God is like? Look at Jesus Christ as He is presented in the pages of the New Testament. I promise that if you do this with an open heart and mind, your life will never be the same.
