[Nikas777]

The plasm Christ was reciting was prophetic but being a psalm it was put in poetic words to be sung so you had a poetic image. Being in that style while the protagonist sings in the first person about being forsaken in reality the psalm shows that the singer is really not forsaken.

It is like that old poster where there is footprints in the sand and Jesus was carrying you all along when you assumed he was not.

[Rutles4Ever]

The plasm Christ was reciting was prophetic but being a psalm it was put in poetic words to be sung so you had a poetic image. Being in that style while the protagonist sings in the first person about being forsaken in reality the psalm shows that the singer is really not forsaken.

So we come back to the question: what is the psalm prophesying, and why is it relevant to Christ, since He's the one who is chanting it, as it were.
