Isn’t God the one who urges us to “Make a joyful noise unto the Lord”? Why do we always think that means singing? Seems to me the most obvious joyful sound on earth is laughter… I’ve seen folks quote verses like “Rejoice in the Lord always” while their faces look like they just buried a rich uncle who willed everything to his pregnant guinea pig. Something is missing.

Charles Haddon Spurgeon

There are also many expressions which may provoke a smile: but let it be remembered that every man has his moments when his lighter feelings indulge themselves, and the preacher must be allowed to have the same passions as his fellow-men; and since he lives in the pulpit more than anywhere else, it is but natural that his whole man should be there developed; besides, he is not quite sure about a smile being a sin, and, at any rate, he thinks it less a crime to cause a momentary laughter than a half-hour’s profound slumber.
