The love of the greater number will grow cold. —Matt. 24:12
And what, specifically, does that mean? Love for God, a person's fellow man, family, art, or.....? And how much is a "greater number"? 55%, 70%, 90%? These kind of scriptures are vague, and can mean anything, just like that fortune you get in a fortune cookie.
But beware allowing the JWs convincing you that it's a dire prediction for the future, and that you have to do anything about it.
