You must ask for God's help. Even when you have done so, it may seem to you for a long time that no help, or less help than you need, is being given. Never mind. After each failure, ask forgiveness, pick yourself up, and try again. Very often what God first helps us towards is not the virtue itself but just this power of always trying again.
C. S. LewisWhen we see the face of God we shall know that we have always known it. He has been a party to, has made, sustained and moved moment by moment within, all our earthly experiences of innocent love.
C. S. LewisAbove all, do not attempt to use science (I mean, the real sciences) as a defence against Christianity. They will positively encourage him to think about realities he canโt touch and see.
C. S. LewisAll the delights of sense, or heart, or intellect, with which you could once have tempted him, even the delights of virtue itself, now seem to him in comparison but as the half nauseous attractions of a raddled harlot would seem to a man who hears that his true beloved whom he has loved all his life and whom he had believed to be dead is alive and even now at his door.
C. S. LewisOne of our great allies at present is the Church itself. Do not misunderstand me. I do not mean the Church as we see her spread out through all time and space and rooted in eternity, terrible as an army with banners. That, I confess, is a spectacle which makes our boldest tempters uneasy. But fortunately it is quite invisible to these humans.
