Christmas is considered a time to be joyful and thankful because of Jesus coming into this world. One famous him starts "Joyful, Joyful, we adore thee." Because Christ saved us from our sins, we can live a joyous life on earth.
Therefore, it is most reprehensible that UBF always fostered an environment of misery. There was no time to be joyful for anything. We constantly had to think about how we were not obedient enough, thankful enough, feeding enough sheep, fishing enough, losing enough weight, or coming to prayer meetings early enough. In UBF, the hymn should have been, "Miserable, Miserable, we adore thee." The message was that we must be miserable all the time. Even if we "feed 12 sheep" and came to every meeting, the leaders would stomp on any evidence of joy with rebukes and training. Personally, I always had to repent for being overweight and not having enough sheep.
I have learned since leaving UBF that Jesus did not come down from his throne in Heaven to die on the cross for my sins and give me eternal life in Heaven so that I could spend the rest of my human life feeling miserable about my shortcomings. Jesus did not allow himself to be nailed to the cross so that I could go through life thinking that I am a fat, insensitive jerk. Christ brought victory over all of my shortcomings. Christ put them on the cross and covered them with his blood. Christ calls me to remember how great he is rather than how terrible I am. Then, I am filled with joy in my salvation.
