This book is a collection of essays by the Puritan thinker Thomas Boston, on a theme which the title probably makes clear enough. I've been reading this through with my dad and have found the experience soundly edifying and an effective mode of discipleship, intellectually and spiritually. Boston's prose, though old, is not archaic, and thus relatively easy to read and interpret. The points he makes are very gospel-grounded; I don't think anything in this book would be at all controversial to most orthodox Christians, and I do think that much of what is in here would be of great help to those same in the deepening of their conviction as regards their union with Christ, as is the gist of the New Testament.
