[I'm using some model dinosaurs my brother and I made when we were kids.]
The point of the sermon is to make the connection between how I have looked after the models all these years because I made them, and how God intends to keep everything that God has made as well. Not lose any of it. That's the point of Jesus.
Points to emphasise: I made the models, a lot of time and effort, painted them etc., and I have carefully kept them in this box all these years. As I have moved from house to house, carefully they have been moved as well.
Parallel: God made everything, carefully, loves everything, and does not intend to lose any of it. In fact, God wants to bring it all home, back to God. That is why God sent Jesus.
