Guy Prentise Waters gave two interesting messages on some very important doctrinal points that play heavily in justification. Waters compares and contrasts Adam and Christ, the Old Covenant and the New, and the implications they have in terms of righteousness.
While I love Guy Prentise Waters, these two messages required more than the usual amount of attention. They are lectures, and as such, are a bit on the dry and monotone side of things. The information is great. But the format of the delivery will require work for the listener. Not commuter friendly audio. Be warned.
