“Parents can tell but never teach, unless they practice what they preach.”
“...No one teaches well unless he has first learned well; no one learns well unless he learns in order to teach. And both learning and teaching are vain and unprofitable unless accompanied by practice.”
“I don't practice what I preach because I'm not the kind of person I'm preaching to.”
“Teach don't preach!”
“We have in fact, two kinds of morality, side by side: one which we preach, but do not practice, and another which we practice, but seldom preach.”
“We accept what Scripture teaches as far as our doctrine is concerned; but when it comes to practice, we very often fail to take the Scriptures as our only guide. ... Dare I give an obvious illustration? The question of women preaching, and being ordained to the full ministry.”
