"These are the hidden sayings that the living Jesus spoke and that Didymus Judas Thomas wrote down.

1. And he said, "Whoever finds the correct interpretation of these sayings will never die."

2. Jesus said, "The seeker should not stop until he finds. When he does find he will be disturbed. After having been disturbed, he will be astonished. Then he will reign over everything. [Having reigned, he will rest.]"
