There are times when we feel drained, even when our bodies are well-fed. When we only work for our own gain or our own agenda, we often find ourselves longing for something deeper, something that satisfies the soul beyond what any earthly provision can offer. Jesus pointed to a source of strength and satisfaction that goes beyond food or drink and beyond the satisfaction that comes from working for our agenda—this is a nourishment that comes from living out God's will. This deeper fulfillment is available to us as we align our lives with His purpose.

John 4:34 (KJV):

Jesus saith unto them, My meat is to do the will of him that sent me, and to finish his work.
