As the plants come up so do the weeds, which require removal and more work. The farmer is constantly working the soil in order that healthy plants will grow out of it and produce quality fruit. Healthy plants require healthy soil in which to grow. They draw from the nutrients in the soil for nourishment and sustenance, in order to be healthy. A master gardener knows how important it is to be constantly feeding the microorganisms in the soil, which in turn feed the plants.
Fertile soil is a prerequisite for healthy plants.
Prayer is the soil in which the plantings of the Lord can germinate, take root and grow into strong healthy plants, which will bear quality fruit in great quantities. The unplowed ground needs to be worked before the harvest will be produced. It is the work. In all work for God, prayer is the working power of all that God would do through His people. Prayer is the fertile soil or seedbed of the spiritual environment necessary for healthy plants to grow.
