I attend the Grand Rapids, Michigan congregation.
Normally services are at 2:30 PM on the sabbath. The 3rd sabbath of the month (today for example) we combine with our Kalamazoo congregation in a hall in Plainwell, Michigan.
I checked out the web site and see that you have all the sermons online there. I don’t have time to listen to them all but one piqued my curiosity. What exactly is the unpardonable sin that is mentioned as one of the sermon titles?
