Truth
Everything is as good or as bad as our opinion makes it. (C S. Lewis, late British professor)
That fits well with what author Herbert V. Prochnow wrote: “A great many people mistake opinions for thought.” It seems that authoritative truth doesn’t exist anymore. Whatever you think is true is okay. The problem comes, of course, when differing opinions are expressed. It’s necessary, then, to have a reliable source of truth from which to judge opinions.
Teach me your ways, O Lord, that I may live according to your truth! . . . The very essence of your words is truth; all your just regulations will stand forever. (Psalm 86:11; 119:160)
