The Puritans believed that God blessed them with the lands of the New World. Their main justification for taking Indian land was that the Native American populations were not using the land effectively, so it was their divine right to take the lands that belonged to the Native Americans.  Since the Native Americans did not understand land ownership in the same way that the English did, it was not as difficult to take it from them.  The Indians did not build cities or towns and the land looked to be undeveloped in the eyes of the Puritans.  The colonists believed that the land was being under-utilized and that they were actually providing the Indians with a service by civilizing their culture.  In quoting scriptures from the Bible, like the one referenced above, the Puritans felt a sense of moral calm in taking the land from the Native Americans.
