Can Belief in God Be Confirmed?

A basic thrust behind Alvin Plantinga\u27s position that belief in God is properly basic is an analogy between certain non-religious (and presumably justified) beliefs such as \u27 I see a tree\u27 and theistic beliefs such as \u27God made this flower\u27.1 Each kind of belief is justified for a believer, argues Plantinga, when she finds herself in a certain set of conditions. Richard Grigg challenges this claim by arguing that while the non-religious beliefs are confirmed, beliefs about God are not. I wish to explore this challenge, clarify it and suggest that on one understanding it is irrelevant and on another it is false
