"The integrity of the upright shall guide them: but the perverseness of transgressors shall destroy them." (Prov. 11:3) " The righteous man walks in his integrity; his children are blessed after him." (Prov. 20:7)

Dr. Madison Sarratt, taught mathematics at Vanderbilt University for many years. Before giving a test, the professor would admonish his class: "Today I am giving two examinations - one in trigonometry and the other in honesty. I hope you will pass them both. If you must fail one, fail trigonometry. There are many good people in the world who can't pass trig, but there are no good people in the world who cannot pass the examination of honesty."
