David. R. Goodworth explores saying 1.2/Th 3 from his book 'The Gospel of Thomas: Evolution'

“If those who lead you say to you ‘Behold the Kingdom is in the sky’ then the birds of the sky will get there before you. If they say to you ‘It is in the sea’ then the fish will enter before you. Rather the Kingdom is inside you and outside you. When you come to know yourselves, then you will be known, and you will realise that you are the children of the living Father. But if you do not know yourselves, then you will dwell in poverty, and you are that poverty.”
