First comes deed, then word; for no word of teaching is approved unless first he who teaches shews himself to be a doer thereof. For acting goes before sight; for unless by thy works thou hast cleansed the glass of the understanding, the desired brightness does not appear. But still further it is added, Before God and all the people. For first of all we must please God, and then have regard as far as we can to honesty before men, that placing the honour of God first, we may live without offence to mankind.
