" Jesus. Do not permit sinners to hear sermons as a matter of course, or allow them to play with the edged tools of Scripture as if they were mere toys; but again and again remind them that every true gospel sermon leaves them worse if it does not make them better. Their unbelief is a daily, hourly sin; never let them infer from your teaching that they are to be pitied for continuing to make God a liar by rejecting his Son. "
