Jesus kept on teaching and said, “Let me tell you another story about how God is growing a family for himself. He is doing that so that he can look after his family forever. A man wanted to grow some food, so he got the ground ready and spread the seeds all over that ground. When he finished, he walked away and left those seeds to grow. The man did not know what made those seeds grow, but day and night for many months, the seeds grew and became plants. First the seed went into the ground and then the plants grew out from those seeds. At the right time, the plants grew new seeds, and when those seeds had finished growing, the man cut those plants. He hit the plants so that the seeds fell off, then he picked up all the seeds and put them into his shed.” And you can read this story in Matthew 13:31-32, 34 and in Luke 13:18-19
