In the book Conversations With God, Neale Walsh writes his answer from God about the two deepest emotions that motivate humans – love and fear.
“And here is how human behavior produces repeat experience after repeat experience; it is why humans love, then destroy, then love again: always there is the swing from one emotion to the other. Love sponsors fear sponsors love sponsors fear.
And the reason is found in the first lie—the lie which you hold as the truth about God—that God cannot be trusted; that God’s love cannot be depended upon; that God’s acceptance of you is conditional; that the ultimate outcome is thus in doubt. For if you cannot depend on God’s love to always be there, on whose love can you depend? If God retreats and withdraws when you do not perform properly, will not mere mortals also?
And so it is that in the moment you pledge your highest love, you greet your greatest fear.
For the first thing you worry about after saying “I love you” is whether you’ll hear it back. And if you hear it back, then you begin immediately to worry that the love you have just found, you will lose. And so all action becomes a reaction—defense against loss—even as you seek to defend yourself against the loss of God.
Yet if you knew Who You Are—that you are the most magnificent, the most remarkable, the most splendid being God has ever created—you would never fear. For who could reject such wondrous magnificence? Not even God could find fault in such a being.”
