This is the water and this is the well

Drink full and descend

The horse is the white of the eye and dark within 

Through the dark of Futures Past the magician longs to see

One chance out between two worlds

Fire walk with me

If you reverse the Futures Past poem, it parallels the woodsman’s poem.

The darkness within is the darkness of Future Past

The eye of the horse is the white of the eye and the magician longs to see

One chance out between two worlds, and drink full and descend (that is, travel between realms)

This is the water and this is the well, and fire walk with me (travel between the rounds through the elements, via water or fire) 

Matthew 3:11 – I indeed baptize you with water unto repentance: but he that cometh after me is mightier than I, whose shoes I am not worthy to bear: he shall baptize you with the Holy Ghost, and [with] fire.
Note that the Woodsman is named Gabriel, who announced to Mary that she would bear the Christ child. The scripture first is from John the Baptist, who was talking about Christ. 
As a rough idea, this understanding fit somewhat with the idea of Bob/Mr C as Antichrist, and Laura as the Christ figure.
