God will help…

Have hope and firm faith in God, for he will help you in everything. Pray to him, humble yourself under his great power, because, without a doubt, as he has given you this charge, so he will give you also the strength to be able to carry it out.
–Saint Angela Merici (1474-1540)

Grace of God…

Bear in mind that one who is able to restrain himself or to do any other good thing does not do it by virtue of his own strength: it is the grace of God that empowers the person.
–The Desert Fathers (and Mothers)
