UL 138.4
(The Upward Look 138.4)
There are many things which are right in themselves, but which, perverted by Satan, prove a snare to the unwary. The gathering together of our youth for a singing exercise sounds very harmless, but it has been my experience, during half a century, that these singing exercises often prove a source of much harm to souls. If the hearts of all who attend were right with God; if all loved God supremely, and desired to keep His glory in view; if all would strive to please Him, then such exercises would not prove harmful. But usually there are present many who do not realize that they are becoming more and still more unconcerned regarding their duty to please God. Their souls become indifferent. One has an influence over another, and the indifference manifested toward spiritual things increases. God’s Holy Word is not studied diligently day by day, and because of lack of spiritual food, they grow weak in moral power.... (UL 138.4) MC VC
