Sermon for Reformation Sunday (Observed). The hymn "Salvation unto Us Has Come" by Paul Speratus is a sermon in and of itself showing how we are freed from our slavery to sin (John 8:31-36) by Jesus, our Savior.
Speratus included a list of Scripture passages that were the basis for his hymn. You can find those verses here.
Our apologies that the congregational singing has such a low volume. Hopefully, it will still be audible.
