(Matthew 13:47-50) 47 "Again, the kingdom of heaven is like a net which was thrown into the sea and gathered fish of every kind; 48 when it was full, men drew it ashore and sat down and sorted the good into vessels but threw away the bad. 49 So it will be at the close of the age. The angels will come out and separate the evil from the righteous, 50 and throw them into the furnace of fire; there men will weep and gnash their teeth. 51 "Have you understood all this?" They said to him, "Yes." 52 And he said to them, "Therefore every scribe who has been trained for the kingdom of heaven is like a householder who brings out of his treasure what is new and what is old." 53 And when Jesus had finished these parables, he went away from there.
Mark 4:26-29 26 And he said, "The kingdom of God is as if a man should scatter seed upon the ground, 27 and should sleep and rise night and day, and the seed should sprout and grow, he knows not how. 28 The earth produces of itself, first the blade, then the ear, then the full grain in the ear. 29 But when the grain is ripe, at once he puts in the sickle, because the harvest has come."
(John 12:24-26) 24 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. 25 He who loves his life loses it, and he who hates his life in this world will keep it for eternal life. 26 If any one serves me, he must follow me; and where I am, there shall my servant be also; if any one serves me, the Father will honor him.
