I don't know if you are being sarcastic or what.The one single thing that you can say about his spirituality is that he is reading through his Bible once a month?
Sorry.
Completely unqualified.
I know I was way older than eighteen when I read the Bible in it's entirety. Then again, I was pretty unqualified when I got married at 25.
Moreover, I didn't say the kid is qualified to be a husband, just that he is headed in a good direction, and if he keeps it up will be ready in a few years.
In addition, the Bible reading is not the only thing I said about spiritually. I also said that he is very respectful towards elders, and at least inferred that he is diligent/hard working, and has the wisdom of avoiding college foolishness and debt.
