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.

He who does little, but in a state to which God calls him, does more than he who labors much, but in a state which he has thoughtlessly chosen: a cripple limping in the right way is better than a racer out of it.

Whoever seems to himself to have understood the Scriptures in such a way that he does not build up that double love of God and neighbor has not yet understood.

People travel to marvel at the mountains, seas, rivers and stars and they pass right by themselves without astonishment.

This world's a bubble.

Only He who made man makes man happy.

You say to me 'Show me your God.' I answer you, 'Everything you see in your heart that might sadden God, remove.'
