Sometimes the cry of narrow-mindedness seems to induce men and women to lower what they know to be right standards. And yet the greatest teacher the world has ever known said, "Strait is the gate, and narrow is the way, which leadeth unto life." This way of true thinking and successful living is broad enough to admit the infinity of good, narrow enough to exclude all evil.
Unquestionably the way of rectitude and integrity, of morality and purity, seems narrow to the worldly, lax, and materially-minded. But the Christian Scientist, who has promised to be pure, just, and merciful, has a very different standard from these.
We do not call the engineer narrow-minded because he follows without deviation the exact rules of engineering. The chemist who, in order to be broad-minded, deserted his formula and added to or took from it, to please some ignorant advising friend, would not be considered broad-minded, but foolish, perhaps criminally negligent—a menace to mankind.
