To the irreligious person heaven would be hell.

Now what is it moves our very hearts, and sickens us so much at cruelty shown to poor brutes? I suppose this first, that they have done no harm; next, that they have no power whatever of resistance; it is the cowardice and tyranny of which they are the victims which makes their sufferings so especially touching.

Great things are done by devotion to one idea.

God knows what is my greatest happiness, but I do not. There is no rule about what is happy and good; what suits one would not suit another. And the ways by which perfection is reached vary very much; the medicines necessary for our souls are very different from each other. Thus God leads us by strange ways; we know He wills our happiness, but we neither know what our happiness is, nor the way. We are blind; left to ourselves we should take the wrong way; we must leave it to Him.

God created you to do him some particular service. He has given some work to you that he has not given to another. You have your mission. You shall do good.

Without self-knowledge you have no root in yourselves personally; you may endure for a time, but under affliction or persecution your faith will not last. This is why many in this age (and in every age) become infidels, heretics, schismatics, disloyal despisers of the Church. They cast off the form of truth, because it never has been to them more than a form. They endure not, because they never have tasted that the Lord is gracious; and they never have had experience of His power and love, because they have never known their own weakness and need.
