This article attempts to remove some of the mysticism that often surrounds the subject of worship. The normal sequence of a person's inner functions is briefly noted, as well as the basic meanings of the two key biblical words for worship. Worship is then defined with these two key words and the model of inner functions in mind, and three modes of worship are identified. Then worship "in spirit and truth" is discussed. Finally, several practical implications are suggested, both for the individual worshipper and for the leader/planner of worship.
