When Jesus told stories they had double meaning. In Mark 4 there is the parable of the farmer growing his crop.
Christians sow seeds of God’s love. We speak of God’s Word. God’s Word will always produce results and a harvest.
26 Jesus also said, “The Kingdom of God is like a farmer who scatters seed on the ground. 27 Night and day, while he’s asleep or awake, the seed sprouts and grows, but he does not understand how it happens. 28 The earth produces the crops on its own. First a leaf blade pushes through, then the heads of wheat are formed, and finally the grain ripens. 29 And as soon as the grain is ready, the farmer comes and harvests it with a sickle, for the harvest time has come.”
