I usually mention to hyper-Calvinists that the Great Commission makes no sense if such were true.
Again - that statement about the great commission is logical which is what I try and ascribe to.
I don’t worry about any of us being exactly right - the truth is that much of what is spiritual is likely beyond our understanding. Mostly I think christianity is about becoming a loving person - but I think that is too hard for most people so they go the legalistic route (I can’t hardly blame them - it is very hard to be loving).
There is something extremely fascinating about christianity and for me it is the idea of the atonement - that one can stand in for another. It affects me on a gut level. It just has the ring of truth to it.
Most of the other trappings of religion I don’t even care about. For myself I keep to the basics, like the nicene creed - it’s what I feel is the core and most important part. Beyond that I have no clue.
