December 22 Daily Devotional

Set a guard over my mouth, O LORD; keep watch over the door of my lips. Even persons of the most self-possessed temper, if unwarrantably injured, will sometimes proceed to make retaliation, through their resenting the unbecoming conduct of their enemies. In committing himself to the guidance of God, both as to thoughts and words, David acknowledges the need of the influence of the Spirit for the regulation of his tongue and of his mind, particularly when tempted to be exasperated by the insolence of opposition. If, on the one hand, the tongue be liable to slip and too fast of utterance, unless continually watched and guarded by God; on the other, there are disorderly affections of an inward kind which require to be restrained. What a busy workshop is the heart of man, and what a host of devices is there manufactured every moment! If God do not watch over our heart and tongue, there will confessedly be no bounds to words and thoughts of a sinful kind,—so rare a gift of the Spirit is moderation in language, while Satan is ever making suggestions which will be readily and easily complied with, unless God prevent. It need not seem absurd to speak of God inclining our hearts to evil, since these are in his hand, to turn them wheresoever he wills at his pleasure. Not that he himself prompts them to evil desires, but as according to his secret judgments he surrenders and effectually gives over the wicked to Satan's tyranny, he is properly said to blind and harden them. The blame of their sins rests with men themselves, and the lust which is in them; and, as they are carried out to good or evil by a natural desire, it is not from any external impulse that they incline to what is evil, but spontaneously and of their own corruption.
