“Change is the characteristic of all growth. From drinking to sobriety, from dishonesty to honesty, from conflict to serenity, from hate to love, from childish dependence to adult responsibility- all this and infinitely more represent change for the better.
“Such changes are accomplished by a belief in and a practice of sound principles. Here we must needs discard bad or ineffective principles in favor of good ones that work. Even good principles can sometimes be displaced by the discovery of still better ones.
“Only God is unchanging; only He has all the truth there is.”
-Letter, 1966
