It is as impossible for man to demonstrate the existence of God as it would be for even Sherlock Holmes to demonstrate the existence of Arthur Conan Doyle.
Frederick BuechnerWhenever you find tears in your eyes, especially unexpected tears, it is well to pay the closest attention. They are not only telling you something about the secret of who you are but, more often than not, God is speaking to you through them of the mystery of where you have come from and is summoning you to where, if your soul is to be saved, you should go to next.
