Answer:
Belief in God above all else, Native American interactions, and record of Puritan life.
Step-by-step explanation:
The sentence "I cannot but take notice of the wonderful mercy of God to me in those afflictions, in sending me a Bible." shows belief in God, the sentence "I was glad of it, and asked him, whether he thought the Indians would let me read?" shows Native American interactions, and the entire passage is a record of puritan life.
