It's very difficult to find a Christian with integrity, viz: one that can give you a direct answer to a direct question about their beliefs and practices.
When a rational skeptic points out that some of God's actions are not only unreasonable, but also downright evil, selfish, and sadistic; the average Christian typically circles the wagons, i.e. they become defensive. Instead of forthrightly agreeing that the critical thinker's appraisals make sense; the defensive Christian waxes eloquent with a bombastic discourse, deftly concealing the unspeakable truth that they too have sometimes entertained the very same opinions.
I sincerely believe God appreciates honesty and totally despises deceit. So; if perchance the day comes when God asks each of us point blank:
Was there ever a time when you felt that some of my actions were unreasonable, unfair, inhumane, selfish, cruel, and/or the work of a mad man?
Was there ever at time when you wished I didn't exist?
The answers coming out of our mouths better not be what we think He wants to hear, or some scripted response learned in church, rather; exactly what He knows already, i.e. it had better not be equivocation, sophistry, or tiresome rhetoric, no, it had better be a crisp Yes or a No; and it had better be honest.
