How can you believe things like a man coming back from the dead, bringing a corpse back to life, walking on water, instantly healing the sick and disabled, changing the weather, ascending to heaven (did he float up into the air or what?), etc. literally happened, as historical events?
Seriously. This perplexes me.
From Gnostic perspective, the same can (or is) asked about anything in the past. Exploring this, for all it is worth, both philosophically and spiritually, is truly eye opening. Lest one is lazy intellectual and/or willing to just go by (truly blind) faith alone, the idea of not exploring it, is itself perplexing. Especially given the ramifications of repeating mistakes/errors, that are seemingly, or consistently, put forth as "not my doing."
If someone was literally doing that stuff, it would be the biggest thing in the history of the world. Corpses coming back to life and walking around! But the only writings about are mythological writings from Christians, decades later at best. No one else noticed? Everyone just forgot? That's just irrational. If you make the claims that those things literally happened, I would expect some rather amazing evidence. But, we have nothing. What's going on here?
The writing and telling of things from the past passes as "communication," but it truly is not. If somehow, what I'm conveying here is either easily overlooked, I'd identify that as being intellectually lazy. Or if seeing it as actual communication and easy to take for granted (that the past exists), I'd call that blind faith. Could be something that is rather simple, such as, "yesterday I went to the store." Sure seems to communicate a past exists, and that I was there. But where, really? It's actually about as informative as, "last night in my dream, you were there, and you told me you never really loved your mom." The latter is seemingly easily dismissed because of the words "in my dream" when the past account of anything/everything is not actually different. At best, it is all recollection of an interpretation. From a perspective that readily admits then (or even now) it doesn't have full awareness/understanding of "who am I?" and/or "what is life in this existence for?"
Now, if you take these things as metaphor or otherwise non-literally, that's fine, but this thread isn't directed towards that crowd.
I take these things with a grain of salt, considering the messenger has words saying, "things things and more you will do." To place that person in a position of 'specialness' along lines of super human is truly missing the forest for the trees.
Given new age Gnostic understandings, of which I am routinely surprised that I'm seemingly one of a few that is aware of such understandings, it is bizarre to identify much of this as reason to believe this is what makes Jesus, Christ-like.
IOW, walking on water, resurrecting the physical dead, changing weather, etc. are not miracles. They either offer nothing to the follower, or what they convey is spectacles of wonder that distract from the spiritual. Perhaps put another way, why (rather than how) walk on water, why raise the physical life from the dead? Of what purpose is it for me to believe in such things?
Seemingly, the purpose has been to put Jesus on a pedestal, or right next to Creator God as if he alone is worthy of such a position, and none else.
In spiritual reality, we are all in that position and unless what is greatly distorting view of own self is interpretation of "history," there's very little reason (I'd say none) to suggest we have ever left that position. And still, the message seemingly falls on deaf ears, as if the (inner) guru can identify perfection, in another, and somehow is devoid of seeing that in own self. History then becomes a crutch, or way of disabling own self, and projecting onto another, separated being (i.e. Jesus) that which is the tale of both humanity (the physical) and Sonship/Creation (the spiritual) needing to do more, be more, have more to return Home, or in that position of at God's side.
Of all the things mentioned in OP, the one that stands out for me is "instantly healing the sick and disabled." Because that I do have experience with, and from perspective that found that natural to do just that, it is not wondrous. In intellectual terms, it is simply giving people back to themselves, their fully aware selves. From the other perspective that relies on doubt (and fear), it is still understood that healers are doing just this. Even medical doctors are at least attempting to give people back to their fully aware selves, and not treating their ability to do so as some magical occurrence of which only a privileged few are able to achieve.
The instant part makes it seem wondrous, I'll grant that, though do have to stipulate that it is a matter of interpretation of own self to realize it as a wonder. I would put forth that this happens far more often than the doubting self may ever care to acknowledge, and happens in ways that physical eyes simply cannot see. Thus, if changing the goal posts (instantly) to, "yeah, but can you make a physically disabled person physically able again? And do it instantly?" - that then pushes the wondrous envelope. And it is around this point where faith takes on a new, far more personal meaning. In scripture, it routinely references, "by your faith are you healed." Which seemingly has two ways of being understood. First way, by your faith in own self as God's Creation (aka Christ) and truly identifying with that, have you corrected the perception of error in what you thought you were seeing, in own self. Second way, by your faith in Jesus or outer being (i.e. medical doctor), you have opened up a magical door, by which your physical self is now physically better than it once was. Therefore, be sure to maintain faith in that outer being.
The first way makes for instantaneousness. The second way is the roundabout, long path to same destination. Either way, you will/we will get there, because in spiritual reality, you never really left.
