Then certain of the scribes and Pharisees answered him, saying, Teacher, we would see a sign from thee. But he answered and said unto them, An evil and adulterous generation seeketh after a sign; and there shall no sign be given it but the sign of Jonah the prophet: for as Jonah was three days and three nights in the belly of the whale; so shall the Son of man be three days and three nights in the heart of the earth. The men of Nineveh shall stand up in the judgment with this generation, and shall condemn it: for they repented at the preaching of Jonah; and behold, a greater than Jonah is here. The queen of the south shall rise up in the judgment with this generation, and shall condemn it: for she came from the ends of the earth to hear the wisdom of Solomon; and behold, a greater than Solomon is here.
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)
