John 12:24

John  12:24 Truly, truly, I say to you, Unless the grain of wheat falls into the ground and dies, it abides alone; but if it dies, it bears much fruit.

According to the principle of the nature, if a grain of wheat is never sown into the earth, it will remain forever as one grain of wheat; but if this grain of wheat is buried into the earth, then it will bear much fruit. 

In the same principle, the Lord Jesus had to go to the cross to die in order to bear much fruit. As the result of the life-releasing death and life-dispensing resurrection of the Lord Jesus, we have become the many sons of God, simply by believing into Jesus and receiving the divine life. Hallelujah! we are the "much fruit"!
