"If the Way Be Full of Trial, Weary Not" is a wonderful hymn by John R. Sweney. Other, more familiar hymns he wrote are "There Is Sunshine in My Soul Today" and "The Lord Is My Light." He was famous not only as a hymn-writer but an enthusiastic choral director. Also, he was known, as someone who could really make a congregation sing. But I decided that it really helps if the congregation actually knows the hymn and the arrangement to get them to sing out.
Later, I had the opportunity to thank Elder Foster for including that sing-along during the meeting. I told him that I thought it was such fun to sing with the choir again and mentioned that I had been in that video as a former Tabernacle Choir member. But I wondered why he chose that unfamiliar hymn to use for our congregation. He said that it was the message he wanted to use for the theme of his talk. He would have just played the video for people to listen to, but understood that if they felt like they were to participate they might actually read and internalize the words better.
Well, I hope that was what happened. I am not so sure judging from the comments I got. I think I may have been a big distraction. One man came up to me and asked if I was a professional singer or something. I told him that I just happened to know that hymn arrangement because I had sung in that video. He said, "I knew it! You had to have been in the Tabernacle Choir. My wife was right. She said that was the only way you would have been able to sing like that." Distraction or not, I still enjoyed singing that wonderful hymn!
