Many of us think of joy as a spontaneous emotion, and perhaps some of us recognize that it’s the mature fruit of the Spirit. Yet God commands all His people to be joyful during the Feast of Tabernacles as they remember His provision in the wilderness. Psychologists and therapists now recognize that joy comes to the grateful, something the Hebrew Bible has been teaching for millennia in the most practical of ways, showing us what it means to be made in God’s image.
