I begin by simply noting that keeping children in worship is hard work. In fact, virtually all fruit that comes from worship stems from hard work. The word “liturgy” itself means the work of the people. Therefore, a meaningful service will demand much from parents.
There is a principle that we as evangelicals must all understand before we even contemplate the question of children in worship. The principle is that worship is to be a dialogue rather than a monologue. You can apply this principle even to the least liturgical congregation. Once a parent sees that worship is to be engaged, he/she will begin to see the purpose of children in it. Worship is not merely an intellectual exercise, it is an act of communication and communion between God and man. God speaks and we respond. If a parent does not see worship as dialogical, but merely a transmission of ideas from the clergy to the people, then he/she will not see the need to keep children in worship.
