David. R. Goodworth explores saying 2.18/Th37 from his book 'The Gospel of Thomas: Evolution'.

His disciples said, “When will you appear to us, and when will we look upon you?”

Jesus said, “When you strip naked and are not ashamed and take your garments and put them beneath your feet like little children and trample them, then you will see the son of the living one and you shall not fear.”
