Walk on Water song

[ccrrox]

Does anyone know what the meaning of this song is? I just listened to it for the first time and it really freaked me out.

Late last night, I went for a walk,
Down by the river near my home.
Couldn't believe, with my own eyes,
And I swear I'll never leave my home again.
I saw a man walking on the water.
Coming right at me from the other side.
Calling out my name; Do not be afraid.
Feet begin to run, pounding in my brain;
I don't want to go; I don't want to go.
No, no, no, no, no...
I don't want to go.
Mmmmmmm...
