Or, to put it another way, we need NOT to be like the disciples who tried to stop the children coming to Jesus to be blessed. Jesus had plenty to say about the place of children in the kingdom of heaven - indeed, he said that it actually belongs to them. It's perhaps for that reason that the enemy will do everything he can to ensure that the children's work in our churches struggles, because the very future of the next generation in the church depends on it. It doesn't matter if the adult services are fantastic, with great worship and wonderful teaching. If the children's groups in the room down the hall are struggling, then the reality is that the whole church is struggling.
Children are part of the body, and if one part suffers, the whole body suffers.
On the other hand, when the children's work is vibrant and exciting, it will benefit the whole of the church. If you are a children's leader, then do share your feelings regularly with a friend or leader who you can trust, and make sure that you don't allow feelings of isolation or frustration to hinder your own spiritual well-being. If you are a parent, pastor, or in some other role in the church, then take the time to regularly encourage those who work with children. Pray for them, serve them in any way you can, and share the responsibility for blessing the children in the church by being a friend to as many of them yourself as you can. In that way, the whole church will grow, and you will be investing in the future of the kingdom, which after all, does belong to the children, and to those who are childlike at heart.
