Resolved, never to speak anything that is ridiculous, sportive, or matter of laughter on the Lord’s day.
This resolution is a little more characteristic of the “puritan lifestyle” most of us know from our high school history textbooks. But before you assume that Edwards is crazy for never speaking anything funny or about sport on Sundays, let’s ask why he would resolve something like this.
He knew that Israel was commanded to have a Sabbath day dedicated to worship (Exodus 20:8-10), and he knew most Christians ignore this today, and skip over where it says the Sabbath day is still in effect (Hebrews 4:1-11). So the question remains? Why would he do this? Because God commanded it, and he wanted to make sure his whole soul was fixed on God for the whole Sabbath day.
No matter whether you agree with him or not about sport or laughter on the Sabbath, the fact remains: a Sabbath day exists still, will you honor it and worship Jesus throughout that day? Or ignore Him?
