The first reason is that it shows a lack of humility to ask to be given what you have never deserved, so I think anyone who asks for this cannot be very humble. A peasant of lowly birth would never dream of wishing to be a king; such a thing seems to him impossible because he does not merit it. Anyone who is humble feels just the same about these other things. I think they will never be bestowed on a person devoid of humility, because before the Lord grants a soul these favours He always gives it a high degree of self-knowledge. And how could one who has such ambitions realize that He is doing him a great favour in not casting him into hell?
