John 12:24, 31-33

Let me make this clear: A single grain of wheat will never be more than a single grain of wheat unless it drops into the ground and dies. Because then it sprouts and produces a great harvest of wheat—all because one grain died.

From this moment on, everything in this world is about to change, for the ruler of this dark world will be overthrown. And I will do this when I am lifted up off the ground and when I draw the hearts of people to gather them to me.” He said this to indicate that he would die by being lifted up on the cross.
