Polytheism: the belief in or worship of more than one god.
I chose this picture because it shows multiple people wearing fancy clothes and with lots of food so I took that to mean it represents people of power or were worshiped.
Agnosticism: a person who believes that nothing is known or can be known of the existence or nature of God or of anything beyond material phenomena; a person who claims neither faith nor disbelief in God.
Opposite of Atheism, I took agnosticism to be neutral so I chose an image that I thought showed that.
Theism: belief in the existence of a god or gods, especially belief in one god as creator of the universe, intervening in it and sustaining a personal relation to his creatures.
This book says the experience of God, and Theism has belief in a very personal experience so since the image showed a book about one, I thought it represented it well.
