Who knew who

LUke 13:22-30 (Jesus' response to the question, "Lord, are there few of us who are saved?")

I healed and sang and walked with you
and used your name to drive out demons
but you say you do not know me.
I was there for all the acts you preformed
and I taught there on the streets
but you've shut the door
and said you never knew me
But I don't know how this
came to be
that some how
everything I did
produced nothing.
Now I'm left to wonder:
who is I who never knew you?
