Wow that keeps coming up again and again ..I am reading "The Holiness of God"...so I brought out my book with the sermon in it..Sinners in the hands of an angry God and read it (Sproul references it in his book)
..You are right no one would give that sermon today..it is not "seeker" friendly..
I'm having trouble putting my finger on it, but what Calvin has wrote in this chapter seems to go against some things he wrote in the previous chapters.....
I'll have to think on it and get back to you when I have some particulars.
