I think it would be Jesus Christ.
Jesus Christ said ...
'I am the light of the world. Whoever follows me will never walk in darkness, but will have the light of life.'
'I am the way and the truth and the life. No-one comes to the Father except through me.'
'I am the resurrection and the life. He who believes in me will live, even though he dies; and whoever lives and believes in me will never die.'
'I am the good shepherd. The good shepherd lays down his life for the sheep.'
'I am the bread of life. He who comes to me will never go hungry, and he who believes in me will never be thirsty.'
What did He mean?
I would talk to him about it.
