Proverbs4:23
Puritan Board Freshman
What books/works would be beneficial to use for sermon prep, if one was to preach through a series on the 52-week Lord days of the Heidelberg Catechism? I have Ursinus' commentary but can not seem to find anything else in print at the moment. I noticed Theodorus Vander Groe work looks to be out of print as well. Thank you
