Rex tremendæ maiestatis,
Qui salvandos salvas gratis,
Salva me, fons pietatis.
King of majesty tremendous,
Who does free salvation send us,
Fount of piety then befriend us !
This is just a little suggestion, in the main thread of the issue, that salvation may at least partly come from our piety which has in turn been our product from Jesus as the fount of piety itself.
