Jesus says that mustard seeds — the small things that you don’t value — are the makings of the kingdom.
Jesus teaches us that Christianity comes down to how we treat people whom we should hate: our enemies. That is how to be like our God. After all, we deserve death. We should be the enemies of God but in his love and mercy he forgives us. So Christianity, then, is a faith practice where we find that, in the place of hatred, is love.
