by your mercy
do not let our minds be cast down by any troubles of this life,
let no hurtful temptation have dominion over them,
let no darkness of unbelief hold them captive.
But, illuminated by the light of your face shining on us,
may we always walk securely
on the sure ground of the true faith.
