The verses of this hymn begin "I knew a man" and the refrain if the familiar verse "what doth if profit a man if he gain the whole world. Can anyone help me find the whole text or tune. Thanks.

Searching for a song beginning

"I met a man in a faraway land..."
and including the refrain "for me, how could it be, for me" or something like that.

Can anyone help me? Thanks sincerely.
