They are called fiery darts, because they are so painful and so pernicious. We all know, in our own experience, the exceedingly painful nature of these fiery darts, and the only way to overcome them is by having the shield of faith. Exceedingly great temptations are often met with, which tend to make us distrust the love and power of our Father; and the only means of meeting these is by faith. The best way to illustrate the meaning of faith, as applied to these temptations, is just to give one or two instances.
For instance, here is a child of God: suppose that he has been regenerated, and for some time has fought manfully against the evil one, and the allurements of this world, But after a time, perhaps two or three years, he begins to be less watchful. What then? He goes back again, and begins to love this present world, and soon the temptation comes. “Well, I am afraid I shall not be successful, and after all I shall lose the battle.” You all know that a child of God may thus be tempted, and how wretched he will be, till he uses the shield of faith to quench this fiery dart of doubt and mistrust. How shall we use the shield of faith? It is stated regarding the children of God, “I will never leave thee nor forsake thee.” This is true regarding all the children of God; and it is true regarding you. How quickly, when this is used with child-like simplicity, does it quench that fiery dart.
Or in the temptation which sometimes comes to the child of God, when he is tempted to think that he may, after all, be lost; how does the word of God suit this? Simply by believing what it declares, “None shall be able to pluck them out of My Father’s hand.” I am one of His sheep, and therefore I cannot be lost. How this will quench the fiery darts of the devil, and give us joy instead of sorrow!
