1 Cor 15:58
Therefore, my beloved brethren, be ye stedfast, unmoveable, always abounding in the work of the Lord, forasmuch as ye know that your labour is not in vain in the Lord.

Mark 4:26-28
So is the kingdom of God, as if a man should cast seed into the ground;

27 And should sleep, and rise night and day, and the seed should spring and grow up, he knoweth not how.

28 For the earth bringeth forth fruit of herself; first the blade, then the ear, after that the full corn in the ear.

The kingdom of God comes in the preaching of the Word, the preaching is as the seed of the kingdom, which sprouts.

Heaven is not far above us in the clouds, it has come down like rain, showering the earth.  It takes the form of seed; little seeds of heaven the Gospel is, when the seed sprouts and grows, it is heaven that blossoms forth from it.

Is the fruit of God in your life?  Is heaven sprouting in your soul?  We wrongly conceive of heaven a place we go.  Jesus brought heaven down to us, not only so, but in His word He planted it in the earth, sowed it everywhere He went, and His ministry has shaped the face of the world.

Let heaven grow in your life – plant the seeds of it all around you: preach the Word, be instant in season, out of season; reprove, rebuke, exhort with all longsuffering and doctrine.

Preach the Gospel.  Change the World.
