This is an encouraging song reminding those of us who believe that Heaven is coming. I thought about those who survived the tornadoes, and now I also think about people going through persecution for the sake of Christ and the Gospel, and even people going through physical pain such as mine (fibromyalgia). I realize the verse Josh Wilson is taking from in mentioning the "weight of glory" is about suffering for the sake of Christ and the Gospel, but I know that other suffering conforms Christians like me more into being like Christ in a different way.
"Therefore we do not lose heart, but though our outer man is decaying, yet our inner man is being renewed day by day. For momentary, light affliction is producing for us an eternal weight of glory far beyond all comparison, while we look not at the things which are seen, but at the things which are not seen; for the things which are seen are temporal, but the things which are not seen are eternal." 2 Corinthians 4:16-18
I hope this song will encourage other people too. I think we sang it at least once at the church I attend, if I'm remembering right that is!
