This is a Taizé chant and in Gather 3rd ed. they have the refrain in English, Spanish and Swedish and verses in English and Spanish. It is based on Psalm 63:1-4,7-8 and John 7:37-39 and credited to the Taizé community.
GIA only sell the handbell version that I can find, but Hymnary lists the hymnals in which this song is found and the lyrics are in the previews there. Cantus Mundi has some background information as well.
If you go to the Taizé site and click on “Kristus, din Ande”, they give all the words and practice melody lines for each part of the chant.
I just did a backing for the ostinato refrain.
