What is Reformed Theology? R.C. Sproul answers this question in twelve lectures available here. [If the videos do not come out at first click on the pop out button and it should work].
I find it weird posting stuff that I have not watched, heard, or read. I haven’t seen these videos yet, but heard the audios awhile back. I forget if Dr. Sproul talks about the Gospel sacraments, but without a doubt Sproul has audios and videos on the Gospel sacraments elsewhere.
