This song with a text by Deborah D. Smith and music by Michael W. Smith is not for liturgy but is the sort of song that makes everyone cry at the end of a school year or for other partings. It is very much a solo vehicle and shares some music ideas with “Lying Eyes” by the Eagles and “You’re My Home” by Billy Joel. It is apparently very popular.
According to this story it was written quickly and it has hallmarks of that. (eg “and friends are friends forever if the Lord’s the Lord of them”)
