Mark 4:26-29 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.”
Let’s say you have one melon seed that you could eat, but it would not benefit you much. Or you could plant the seed and let it grow which would yield a few melons full of seeds. Now you have melons to eat and the opportunity to plant more seeds, in turn now you will have a small field of melons and now hundreds of seeds you can now sell including the melons. Those seeds can also be planted again, therefore, you would now have acres of melons.
Do you see what is happening here? This is the law of seedtime and harvest.
Genesis 8:22 While the earth remaineth seedtime and harvest, and cold and heat, and summer and winter, and day and night shall not cease.
It’s the same thing when you plant a seed into God’s Kingdom. It can be your time, talent or your resources. This manifests in many folds, it not only helps others, but you get the blessing from the seed which keeps multiplying within the Kingdom of God.
