God's Cultivated Land

I was reading some ministry today. Something about "Being God's cultivated land" and being the sowers who sow the seed.
I don't know why I read the book entitled The Holy Word for Morning Revival. It makes me feel I have a purpose, I suppose. A reason for living. Maybe that makes me weak. But I am weak, and that's ok. I just feel more open to life by praying some of the verses and somehow it's ok that I don't really believe that much.
So I enjoyed the phrase that proclaimed us as the cultivated land for God. We are His spiritual land, in which His seed grows. The reading ended with "is still all a mystery to natural man," of course. I guess if reading verses helps us we should do it, even if we don't understand it. For example, the children of Isreal not eating things without cloven hoofs without knowing why they were dirty. Pigs actually had more bacteria than cows or other animals with cloven hoofs, thereby keeping the children of Isreal safe from infectious material.
