And he said, So is the kingdom of God, as if a man should cast seed upon the earth; and should sleep and rise night and day, and the seed should spring up and grow, he knoweth not how. The earth beareth fruit of herself; first the blade, then the ear, then the full grain in the ear. But when the fruit is ripe, straightway he putteth forth the sickle, because the harvest is come.
Jesus told him, "I am the way, the truth, and the life. No one can come to the Father except through me." (John 14:6)
