We are now starting to making videos of the hymns (performed by the Northern Christadelphian Choir) in English with a Farsi translation (either for understanding or for singing) available!
We're still uploading these and more are being created, the growing list of hymns available in Farsi is here: https://www.isolationleague.org/hymns/list/farsi (you need to be logged on to the website to view this).
