My goal here is not to argue that Christianity is true, but that I'm reasonable to be a Christian. I don't care if you agree with me about Christianity, but I do want to persuade you that I'm not stupid, crazy, insane, or in any other epistemically lamentable state, for being a Christian. What follows is a sketch that I can expand as people ask reasonable questions.
Keeping this as short as reasonably possible, I'm a Christian because I think that God exists and that God resurrected Jesus. As Pascal suggested, if I think both of these claims are probably true, then it makes sense for me to foster a belief in the Christian religion by going to church, praying, and so on. Christianity will be the "best bet" in that event, such that it will make more sense for me to foster a belief in Christianity than to foster a belief in another religion or foster no belief in any religion. So, the question is whether or not I can justify my belief that both of these claims are probably true.
My justification for my belief that God exists is an inductive argument for the existence of God which it isn't easy to express briefly, so I won't try. However, I will say that it pulls on the following versions of the following arguments.
(1) A cosmological argument from the existence of a complex physical universe
(2) A teleological argument from temporal regularity
(3) A teleological argument from spatial regularity, or "fine tuning"
(4) An argument from beauty
(5) An argument from moral awareness
(6) An argument from consciousness
(7) An argument from our ability to make significant decisions, or "providence"
(8) An argument from miracles
(9) An argument from history
The above arguments come together to form a cumulative case which I think is sufficient to justify the following.
(10) Therefore, it is at least as likely as not that God exists.
I then introduce the following propositions.
(11) If X is as likely as not to exist based on the other evidence, and if additionally I have an experience that seems to be of X, then X probably exists.
(12) I have had experiences that seemed to be of God.
So, from (1)-(9) I inductively infer (10), and from (10), (11) and (12) I deductively infer that God probably exists.
I have my belief that God exists based on the above arguments, but I have my belief in the Resurrection partly in the basic way. The idea of a properly basic belief takes off from the observation that we all have to begin building our structure of knowledge from certain plausible assumptions, and to me, one of these assumptions is that the Resurrection occurred. This, in combination with my belief that God would have reason to resurrect Christ if he had the moral character displayed in the Gospels, seems to me to warrant a belief that God probably resurrected Jesus.
So, given that I think God probably exists and that God probably resurrected Jesus, it's reasonable for me to cultivate a belief in the Christian religion by the methods suggested by Pascal.
