Certainly something better than descriptions of people's feelings about belief and various purely mental experiences, such as the epiphany you (at least my memory is that it was you) described. I really have no access to those things but people's reports on them, and that's not evidence, it's anecdote. If I had witnessed that epiphany, for instance, what would I have noticed? Nothing, really, except possibly someone in a highly charged emotional state. I would not have seen the hand coming down to envelop, nor would I have heard the voice. I'm not denying something significant happened, but I can't detect such things, nobody can but the person experiencing them, and that just isn't evidence.What form do you expect that evidence to take?
Something better than biblical citations too. That's one of the weakest ways to argue for belief, because it presupposes a special status for the Bible, which both begs the question and amounts to no more than an argument from authority. Some of the scripture you cited is certainly true, if Christ is not risen then your faith is vain, but the only evidence Christ rose from the dead is in the text itself, there is no independent corroboration of that claim, and the same claim has been made for others--Osiris, for instance, and more recently a contemporary of Jesus named Appollonius of Tyana--with no better evidence. I presume you don't believe those claims, and you shouldn't, there's no evidence to sustain them, but as I more or less said somewhere else, when you really understand why you don't believe those claims, you'll understand why I don't believe the biblical claims about Jesus.
The statement "There is a god" is really an empirical claim about the nature of the cosmos, in that a cosmos with a god in it ought to be detectably different from one without, essentially because if it's not, then there's no point in or need for god's existence, he's not making any difference and thus his existence is irrelevant. I've read arguments in support of that claim that span thousands of years of human history, and heard or read probably hundreds of people making the arguments to me personally, and none of them hold water on close inspection. They're logically flawed, often by begging the question as the argument from design does, or they're merely anecdote and hearsay, or they're just plain silly, like St. Anselm's ontological argument.
There ought to be some evidence if the claim is true. Asking me to specify beforehand what form it should take is to prejudge it. It is, to paraphrase Sherlock Holmes, a capital mistake to theorize in advance of the evidence. Best I can give you is a vague generalization: it requires some very well attested event that admits of no other conceivable explanation. Stopping and restarting the earth's rotation without causing any damage would do it, and I know the Bible claims that happened at least twice, once in fact reversing it briefly, but that's not well attested enough, nobody else on the planet noticed. One could argue of course that god arranged it so nobody else would notice, but that kind of argument goes nowhere. It means god hides the signs of his existence from reason and evidence, and if he really wants us to know him it doesn't make sense that he'd do that. I have little doubt you'd argue that god endowed us with intelligence, the capacity for reason, and the ability to evaluate evidence, but it seems pretty senseless to me that the only path to him that he allows involves denying them.
