David. R. Goodworth explores saying 6.14/Th107 from his book 'The Gospel of Thomas: Evolution'.

Jesus said, “The kingdom is like a shepherd who had a hundred sheep. The largest one went astray. He left the ninety-nine and sought after the one until he found it. Having gone to so much effort to find it, he said to the sheep, ‘I want you more than the ninety –nine'.
