And yet how many of my readers often have the miserable consciousness that they have 'spoken unadvisedly with their lips'! How many pray, 'Keep the door of my lips,' when the very last thing they think of expecting is that they _will_ be kept! They deliberately make up their minds that hasty words, or foolish words, or exaggerated words, according to their respective temptations, must and will slip out of that door, and that it can't be helped. The extent of the real meaning of their prayer was merely that not quite so many might slip out. As their faith went no farther, the answer went no farther, and so the door was not kept. Do let us look the matter straight in the face. Either we have committed our lips to our Lord, or we have not. This question must be settled first. If not, oh, do not let another hour pass! Take them to Jesus, and ask Him to take them. But when you _have_ committed them to Him, it comes to this,--is He able or is He not able to keep that which you have committed to Him? If He is not able, of course you may as well give up at once, for your own experience has abundantly proved that _you_ are not able, so there is no help for you. But if He is able--nay, thank God there is no '_if_' on this side!--say, rather, _as_ He is able, where was this inevitable necessity of perpetual failure? You have been fancying yourself virtually doomed and fated to it, and therefore you have gone on in it, while all the time His arm was not shortened that it could not save, but you have been limiting the Holy One of Israel. Honestly, now, have you trusted Him to keep your lips _this day?_ Trust necessarily implies expectation that what we have entrusted will be kept. If you have not expected Him to keep, you have not trusted. You may have tried, and tried very hard, but you have not _trusted_, and therefore you have not been kept, and your lips have been the snare of your soul (Prov. xviii. 7). Once I heard a beautiful prayer which I can never forget; it was this: 'Lord, take my lips, and speak through them; take my mind, and think through it; take my heart, and set it on fire.' And this is the way the Master keeps the lips of His servants, by so filling their hearts with His love that the outflow cannot be unloving, by so filling their thoughts that the utterance cannot be un-Christ-like. There must be filling before there _can_ be pouring out; and if there is filling, there _must_ be pouring out, for He hath said, 'Out of the abundance of the heart the mouth speaketh.'
