Reality in God, With Skin On

Reality is had to face at times. But then it’s not like we have a choice. Living in the land of denial doesn’t work. And when it comes to my Faith, some days it just seems to be on vacation.
I will not bore you with all the details of my life. I’ve had my moments of wonder and my moments of terrible. I have a Ph.D. and I still have more questions than answers.
When I was younger I could believe God for anything. Not so much these days. The difference? Life and reality got in my way and blinded me.
The biggest issue I struggle with is divorce and remarriage. If I read the Bible the words seem pretty clear. Unless you have a Biblical reason for a divorce it is wrong. So if it is wrong, what happens to those of us, whose spouse divorced us. If we remarry according to the Bible it is Adultery.
I am not judging anyone here. This is my own personal hell. Surely there is something I am missing. Grace doesn’t extend just to a few, does it?
