We cannot know the whole truth, which belongs to God alone, but our task nevertheless is to seek to know what is true. And if we offend gravely enough against what we know to be true, as by failing badly enough to deal affectionately and responsibly with our land and our neighbors, truth will retaliate with ugliness, poverty, and disease.
And now life has become the future. Every moment of your life is lived for the future-you go to high school so you can go to college so you can get a good job so you can get a nice house so you can't afford to send your kids to college so they can get a good job so they can get a nice house so they can afford to send their kids to college.
Show me a man or a woman alone and I'll show you a saint. Give me two and they'll fall in love. Give me three and they'll invent the charming thing we call 'society'. Give me four and they'll build a pyramid. Give me five and they'll make one an outcast. Give me six and they'll reinvent prejudice. Give me seven and in seven years they'll reinvent warfare. Man may have been made in the image of God, but human society was made in the image of His opposite number, and is always trying to get back home.
There is a criterion by which you can judge whether the thoughts you are thinking and the things you are doing are right for you. The criterion is: Have they brought you inner peace? If they have not, there is something wrong with them -- so keep seeking! If what you do has brought you inner peace, stay with what you believe is right.
