Who Is This Man, Jesus?

Matthew 21:10,11 And when he was come into Jerusalem, all the city was moved, saying, Who is this? And the multitude said, This is Jesus the prophet of Nazareth of Galilee.

C.S. Lewis suggests that there are only three possible answers to who Jesus was and is:

You must make your choice. Either this man Jesus was, and is, the Son of God: or else a madman or something worse. You can shut him up for a fool: you can spit at him and kill him for a demon: or you can fall at his feet and call Him Lord and God. But let us not come with the patronizing nonesense about his being a great human teacher. He has not left that open to us. He did not intend to. 

Jesus is God -- the Messiah, who came to save humanity from their sins. He is the only way to salvation, the only door to heaven, and the only mediator between God and man.

Is Christ your personal Saviour? Why not?
