We have had two rather large gardens on our journey. One in Knoxville and one in Bowling Green, KY. The one in Knoxville was on the side of a hill so we did raised terraces. There was a lot of rocks. So we had to till the soil and remove them. In Bowling Green there was not a lot of rocks but there was a lot of clay. So we had to add a lot of organic material, mulch, manure, and all of that had to be tilled.
So to be good soil or to improve the “soil” that we are, we have to have manure spread on us and that tilled into our lives. Sounds a lot like suffering and discipline to me. Which aligns fairly closely with Hebrews 12 and 1 Peter.
