It is a great book with lots of things to think about. I love the one essay in it called "The End For Which God Created The World." Jonathan Edwards is definitely a challenging read, but He raises your awareness of the greatness of our God. Praise God for theologians like Jonathan Edwards!
The books are excellent. The only negative about them is the small print. However, I think it does all Christians good to read from some of the classical authors, and Johnathan Edwards is one of my very favorites of all time. If one could imitate him, one would do well.
