If anyone considers himself religious and yet does not keep a tight rein on his tongue, he deceives himself and his religion is worthless.... With the tongue we praise our Lord and Father, and with it we curse men, who have been made in God's likeness. Out of the same mouth come praise and cursing. My brothers, this should not be. Can both fresh water and salt water flow from the same spring? My brothers, can a fig tree bear olives, or a grapevine bear figs? Neither can a salt spring produce fresh water.
Thus begins tongue patrol, day 1.
