Note, 1. It is our great concern to keep our souls from straits, being entangled in snares and perplexities, and disquieted with troubles, that we may preserve the possession and enjoyment of ourselves and that our souls may be in frame for the service of God. 2. Those that would keep their souls must keep a watch before the door of their lips, must keep the mouth by temperance, that no forbidden fruit go into it, no stolen waters, that nothing be eaten or drunk to excess; they must keep the tongue also, that no forbidden word go out of the door of the lips, no corrupt communication. By a constant watchfulness over our words we shall prevent abundance of mischiefs which an ungoverned tongue runs men into. Keep thy heart, and that will keep thy tongue from sin; keep thy tongue, and that will keep thy heart from trouble.
