How does Pi manage to keep his faith in God despite unremitting hardships?

Pi comes to the understanding that until he puts his full trust in God he cannot survive. He learns that he needs to trust God, and that God will take care of the rest.

Pi had a hard time at the Pacific. Yet he managed to keep faith in God by reminding himself of God's creation and his place in it. He considered his turban as God's hat, his pants as God's attire, Richard Parker as God's cat and so on.
