I've heard of Dr. Gary Chapman, but I only "met" him now. I discovered his gems a few days ago. The following is one of his great biblically informative teaching videos on marriage enrichment.
Couples should never miss seeing and learning from Dr.Chapman as he expounds the Bible for married couples and also create some fun along the way! I like what he says about "tingles," among many other things, in this video. Really, don't miss it!
