John 12:24, 31-33

Truly, truly, I say to you, unless a grain of wheat falls into the earth and dies, it remains alone; but if it dies, it bears much fruit.

Now judgment is upon this world; now the ruler of this world will be cast out. And I, if I am lifted up from the earth, will draw all men to Myself.” But He was saying this to indicate the kind of death by which He was to die.
