By and by never comes.

Men go forth to marvel at the height of mountains, and the huge waves of the sea, the broad flow of the rivers, the vastness of the ocean, the orbits of the stars, and yet they neglect to marvel at themselves. Variant: Men go abroad to admire the heights of mountains, the mighty billows of the sea, the broad tides of rivers, the compass of the ocean, and the circuits of the stars, and pass themselves by.

Do what you can and pray for what you cannot yet do.

He cannot have God for his Father who will not have the Church for his mother.

If you should ask me what are the ways of God, I would tell you that the first is humility, the second is humility, and the third is humility. Not that there are no other precepts to give, but if humility does not preceed all that we do, our efforts are fruitless.

Often a non-Christian knows something about the earth, the heavens, and the other parts of the world, about the motions and orbits of the stars and even their sizes and distances... and this knowledge he holds with certainty from reason and experience. It is thus offensive and disgraceful for an unbeliever to hear a Christian talk nonsense about such things, claiming that what he is saying is based in Scripture. We should do all that we can to avoid such an embarrassing situation, which people see as ignorance in the Christian and laugh to scorn.
