In Mark 4:26-29 Jesus talks about how a farmer plants seed, then day or night whether the man is a sleep or awake the seed grows.  

“The Kingdom of God is like a farmer who scatters seed on the ground.  Night and day, while he’s asleep or awake, the seed sprouts and grows, but he does not understand how it happens.  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.  And as soon as the grain is ready, the farmer comes and harvests it with a sickle, for the harvest time has come.”

Jesus says this is what the kingdom of God is like, it’s like a farmer who plants seed and night and day that seed grows.  Whether the farmer is at the field or away from the field, the earth produces the crop on its own.

In Genesis 1:11 God said,  

“Let the land produce vegetation: seed-bearing plants and trees on the land that bear fruit with seed in it, according to their various kinds.” And it was so.”

Where something came from is where it finds its life.  From the earth came vegetation and therefore from the earth vegetation finds its source of life.

In Genesis 1:26 God said,

“Let Us make man in Our image, according to Our likeness; let them have dominion over the fish of the sea, over the birds of the air, and over the cattle, over all the earth and over every creeping thing that creeps on the earth.”

Mankind came from God and therefore man finds his source of life in God.  The seed that becomes a stock of ripened grain does so because the seed belongs in the earth.  Likewise the knowledge of God belongs in the heart of man. Therefore when the word of God is planted in man it takes root and brings restoration and transformation because man came from God and finds his true source of life in him.  

It’s natural and normal for a seed to be planted in the ground and for that seed to become what it is created to become.  In the same way it is natural and normal for the true knowledge of God to be planted in the heart of man and for that seed to grow into restoration and transformation.

We plant the seed and God will make it grow.
