There is a story about a boy flying a kite. The kite was so high that it had disappeared into the clouds. A man came by and asked, “Why are you holding on to that string?” The boy said, “I’ve got a kite up there.” The man looked up and said, “I don’t see it.” The boy replied, “Well, I know it’s there because I can feel the tug.”

That’s like the witness of the Holy Spirit within us. We may not always see the evidence, but we feel a tug in our hearts constantly, letting us know that we are in touch with God.
