The song is about change. From once being blind, deaf, and dumb and then understanding the purpose of life. It seems as if the "geek" line is kept in the song on purpose to communicate an awkwardness, and yet a transition in the life of the author. It seems like Jimmy wanted to communicate a definite change in the song after the following line:

"And I am the geek with the alchemists stone."

The rest of the song is obviously about Christ.

The "forget-me-nots in the snow" might be snow angels...

In summary, it's a song of a life of one who once was deaf and blind and then was able to see very clearly the role of man "to ponder his (Christ's) death and his life eternally".
