Like a mother and father who punish a young child, be it spanking, or grounding, or otherwise...and from that child's perspective it is the end of the world....loving parents know it is not, that there are years of life ahead, and the lessons taught and learned by such an experience will benefit that same child in the years to come.
We are God's children and He views us similarly...with love...and there is an eternity before us that we do not comprehend, and rarely appreciate at this point.
That is not a psychosis, just an attempt to grasp that eternal perspective.
Such a position is a noble attempt at a theodicy but doesn't do much good to the six year old dying of leukemia or the wife beaten daily by her husband, et. al.
Why God Godself, if you take the Hebrew Scriptures as revelation, asks me to sit in judgment on God's actions -
"O inhabitants of Jerusalem and men of Judah, judge, I pray you, between me and my vineyard. What could have been done more to my vineyard, that I have not done in it."
To praise God is to assume that we are competent to appraise the good that happens in our lives. To deny that God is a twisted sadist is just the flip side of that.
