Edward A. McDowell, Jr. wrote the words back in 1954. The song is "Ordained of God," and I believe pertains to anyone who has an important message. This certainly includes those of us who are working to address the problems of sexual and domestic abuse. For it is a work of prophecy, and we must never forget this.
I'm offering stanza 1 of the song, since they especially pertain to this work:
"Ordained of God, true Prophets rise. They seek not gain nor earthly prize. They heed the challenge of Christ's call. They ask to give and spend their all."
May we claim our ordination, knowing that this is the only source we need in order to do this work effectively.
