If the greatest commandment is to love God with our whole being, then to come to him in worship is a duty central to living out that love. Worship is not primarily a social occasion as we gather with others to worship, though we are always grateful for the other believers with whom we gather. Worship is not primarily a time for our enjoyment, though being in worship is enjoyable. But worship is primarily an expression of the worth of God. It is a God-centered thing. It is primarily for God and about God; it is not primarily for ourselves and for our needs. Whatever social and psychological benefits it has are secondary. Worship primarily is for God.
David F. Wells, God in the Whirlwind, (Crossway, 2014), 113
