Lord of Our Life and God of Our Salvation

"Lord of Our Life and God of Our Salvation" ("Christe, du Beistand deiner Kreuzgemeine") is a German Christian hymn written by Matthäus Apelles von Löwenstern in 1644. It was translated into English in 1840 by Philip Pusey.

History
The song was written during the Thirty Years' War and published semi-anonymously in Löwenstein's book Früelings-Mayen. He wrote it to plead to God for peace. It's based on Psalm 79:9; Revelation 12:10; Psalm 84:11; Matthew 16:18. It was performed by Johann Sebastian Bach. Almost 200 years later, his hymn was discovered by an English parliamentarian Philip Pusey. He found it applicable to the state of the church in England. He found comfort in Löwenstern's prayer and decided to translate it to English and paraphrase it. It was published in Psalm and Hymn Tunes Alexander Robert Reinagle.
