Billy Graham says, "Whenever anyone asks me how I can be so certain about who and what God really is, I'm reminded of the story of the little boy flying a kite. The wind was brisk and large billowing clouds were blowing across the sky. The kite went up and up until it was entirely hidden by the clouds. "What are you doing?" the man asked the little boy. "I'm flying my kite," he replied.
"Flying your kite?" the man said. "How can you be so sure, you can't see the kite." "No" said the little boy, "I can't see it, but every little while I feel a tug, so I know for sure that it's there!"
