With this description of bradford in mind, what will affect his point-of-view ?

In my opinion, the fact that he "relies on his faith in God to guide his journey" will affect Bradford's point of view. Whatever happens to the Pilgrims, he will interpret as God's will, rather than a consequence of their actions. For example, a disease might be interpreted as God's punishment or temptation, rather than a consequence of poor hygiene. The indigenous people's hostility might be interpreted as a proof what happens to heathens who live without God, rather than a natural behavior of people toward foreign invaders.
