Louis Zamperini said this quote

(after asking Christ into his heart) I waited. And then, true to His promise, He came into my heart and my life. The moment was more than remarkable; it was the most realistic experience I'd ever had. I'm not sure what I expected; perhaps my life or my sins or a great white light would flash before my eyes; perhaps I'd feel a shock like being hit by a bolt of lightning. Instead, I felt no tremendous sensation, just a weightlessness and an enveloping calm that let me know that Christ had come into my heart.
