I wouldn't characterize the latter as confusion ...
It should not be confusing if the thing supposedly causing the confusion is clearly articulated in scripture. Rather, if the thing that is causing the 'confusion' is clearly articulated in scripture, but your human mind (which btw suffers from the effects of sin) cannot comprehend it to some level of human satisfaction ... put that thing in your 'mystery' category.
As multiple posters have adeptly mentioned, it is a mystery why God has perseverance toward us believers while we are yet in this fallen human state ... but the scriptures tells us that He loves us, He is in the process of sanctifying us, and in the future that process will be complete and our own experience of His regenerating power in our lives allows us to just believe that simple truth without fully comprehending it.
I guess what he’s saying, that I got out of it, is that he doesn’t have God all figured out and that he wouldn’t want to.
He’s omni- everything and I’m a mere mortal who can’t even figure out my husband or kids sometimes. Well, most of the time.
Honestly, if we could figure God out, what kind of God would He be? Where would the mystery and awe be and the joy of discovering more about Him?
Not one I’d want to serve.
I think that’s the point he’s trying to get across.
I see a lot of situations in my life and the lives of others around me, that I do NOT understand why God allows them.
