One of the marks of a certain type of bad man is that he cannot give up a thing himself without wanting every one else to give it up. That is not the Christian way. An individual Christian may see fit to give up all sorts of things for special reasons--marriage, or meat, or beer, or the cinema; but the moment he starts saying the things are bad in themselves, or looking down his nose at other people who do use them, he has taken the wrong turning.
C. S. LewisYou 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. LewisThe most dangerous thing you can do is to take any one impulse of your own nature and set it up as the thing you ought to follow at all costs. There is not one of them which will not make us into devils if we set it up as an absolute guide. You might think love of humanity in general was safe, but it is not. If you leave out justice you will find yourself breaking agreements and faking evidence in trials "for the sake of humanity", and become in the end a cruel and treacherous man.
