We heard about Mt. Everest, the highest mountain on planet earth. You may not have seen it, but it's there in Nepal. You will see it if you travel there. The same with God. The fact that you don't see him does not mean that he does not exist. In fact, the existence of God is more certain than that of Mt. Everest. Without God, there wouldn't be Everest. The reason people don't believe is because they have not gone looking for God. By learning about Jesus, studying the Scriptures, praying for guidance and enlightenment...they will begin to find him. And then they'll see that he has been there all along.
