" Most people believe if God performed a miracle—just one miracle—for them, they would surely and permanently believe in God. But, as explained in the commentary to Exodus 16:2, human nature doesn’t work that way. The power of witnessing a miracle wears off quickly, and most individuals soon need (or merely want) another miracle. Over time, most people’s attitude toward those who have done something good for them is: “What have you done for me lately? "
