人好比一粒芥菜种，当你被上帝使用时，你会长成大树，而且还有飞鸟栖息在这树上，能够成为祝福别人的人。
Matthew 13:31-32｜Set he before them, saying, The kingdom of heaven is like unto a grain of mustard seed, which a man took, and sowed in his field: which indeed is less than all seeds; but when it is grown, it is greater than the herbs, and becometh a tree, so that the birds of the heaven come and lodge in the branches thereof.
