We cannot produce crops, only God can. All we can do is scatter the seed on prepared ground, and trust that God will do the miraculous work of growth and fruitfulness. And, when the time is right, we can enjoy the harvest. In the same way spiritually, trust God, have a prepared heart to receive the seed of the Word of God, and then, when the time is right, you will enjoy a great harvest that God brings forth in your life.
(Mark 4:26-29) 26 He also said, “This is what the kingdom of God is like. A man scatters seed on the ground. 27 Night and day, whether he sleeps or gets up, the seed sprouts and grows, though he does not know how. 28 All by itself the soil produces grain—first the stalk, then the head, then the full kernel in the head. 29 As soon as the grain is ripe, he puts the sickle to it, because the harvest has come.”
