This song from Gather 3rd ed. seems to be unavailable from GIA these days – there isn’t even a handbell arrangement left – so if you want it you are probably going to track down one of the hymnals listed at Hymnary, which, thankfully are pretty commonly available.
It has a text from the missionary, Howard S. Olson and a tune by an Ethiopian woman, Almaz Belihu.
It is also available in a collection, Lead Us Lord, which appears to be out of print. Singing from the Lectionary found this sample sheet music.
I have no idea what a 3/8 tune from Ethiopia should sound like – I doubt it should sound so old world. I made a backing anyway.
