"o you desire security? Here you have it. The Lord says to you, 'I will never abandon you, I will always be with you' If a good man made you such a promise, you would trust him. God makes it, and do you doubt? Do you seek a support more sure than the word of God, which is infallible? Surely, He has made the promise, He has written it, He has pledged His word for it, it is most certain.
-- St. Augustine"
