This meme may have been out for a while, but I still find it funny. Part of what makes it so humorous is that it is accurate. I've been through all stages myself.
Having been raised in a Wesleyan-Armininan church, the idea of God's sovereignty over salvation seemed nearly abhorrent to me. However, once confronted with scripture (this about 10-15 years ago while in seminary) I quickly entered the shock and then denial stages. After a few difficult months, I moved on to realization and acceptance. Unfortunately, shortly after that I began that very annoying phase where I tried to convince other unsuspecting Christians that predestination is true. I was, as they say, a bit of a jerk. A cage would have been a good place for me.
I don't know about that last stage. I've never been much of a sage about anything.
A word of clarification: while I strongly hold to Reformed thinking as it pertains to salvation, I disagree with much of it regarding the life and function of the church. Therefore, I'm not really Reformed. Rather, I just love the Doctrines of Grace.
