Once in a while, I have the presence of mind to read a book that is already on my shelf, and that relates to my current pastoral work. Imagine that.
So here is one.
There are 10 essays, in honor of RC Sproul, 5 on the 5 points of Calvinism, as summarized in the Canons of Dordt, and 5 on the 5 solas of the Reformation (only Scripture, faith, grace, Christ, glory to God).
This is an excellent introduction to the Reformed understanding of the Christian faith. Check it out.
