From Thomas...

53 [48]. Jesus says: "If two people are with each other in peace in the same house, they will say to the mountain: 'Move!' and it will move."

(50) Jesus said: If they say to you: Whence have you come?, say to them: We have come from the light, the place where the light came into being of itself. It [established itself], and it revealed itself in their image. If they say to you: Who are you?, say: We are his sons, and we are the elect of the living Father. If they ask you: What is the sign of your Father in you?, say to them: It is movement and rest.
