The language of the law was—“Do this and live.” The language of the gospel is—“Believe on the Lord Jesus Christ, and thou shalt he saved.” Faith in Christ is the prescribed and only condition of acceptance with God. Christ is the way, and the truth, and the life; no man cometh unto the Father but by him. Faith is the eye with which we behold his mercy; faith is the hand by which we receive his blessings; faith is the golden chain which binds us to him for ever. The necessity of faith in the merit and righteousness of our Divine Mediator, as the condition of salvation, is a truth which lies scattered over the surface of inspired Scripture. God has always owned and blessed its proclamation in the conversion of souls. It was the article of Luther’s emancipation from legal bondage. It was the master-key which unlocked the iron gates of Antichrist, and poured the true light over all Europe; so that neither pope nor council, nor both together, could hide it again under a bushel. And in the church of England, even in its present weak and languid state, whenever one of its ministers preaches clearly and faithfully this blessed doctrine, souls are given him as the seals of his ministry.
There is no end to the praises of faith. Faith is the glass that draws fire from the Sun of Righteousness. Faith is the wedding ring that joins the sinner to Christ in an everlasting covenant. Faith is the living principle of all holy obedience, working by love, and purifying the heart. If God command a man to leave his country and his kindred, and go into a strange land—to offer his beloved son as a sacrifice upon the altar—to build an ark on dry ground—to go to the fiery furnace, or the lions’ den—to face his exasperated foes at Jerusalem, or hide from them in the caves of the mountains—it is faith that prompts him to the painful duty, and sustains him therein, in spite of improbabilities; and amidst difficulties, dangers, and deaths.
II. This brings us to notice the importance and utility of faith as a shield. “And above all, taking the shield of faith, wherewith ye shall be able to quench all the fiery darts of the wicked.”
Faith is in some respects the first of all the Christian graces. It is the beginning of spiritual life in the soul—the originating and sustaining principle of all evangelical holiness. Having faith, we have nothing to do but to add to it all the rest of our lives. “Add to your faith virtue, and to virtue knowledge, and to knowledge temperance, and to temperance patience, and to patience godliness, and to godliness brotherly kindness, and to brotherly kindness charity.”
Love is in some respects superior to faith, and shall live and rejoice before the throne when faith shall have finished its work; but faith is an impenetrable shield, such as love cannot furnish, on the field of battle. The shield was a broad piece of defensive armor, worn ordinarily on the left arm; and which, being movable, might be used to defend any part of the body. According to Homer, the shields of some of the warriors at the siege of Troy were made of sevenfold thick bull-hides, covered with brass.
The value of “the shield of faith” is seen in the case of David. Look down there in the valley. There is Goliath of Gath, the chief of the giants, blaspheming, and defying the armies of the living God. His spear is as a weaver’s beam, and his armor-bearer carries before him an enormous shield. And there is a fine-looking young man going down to meet him, without any visible weapons, except his shepherd’s sling, and five smooth stones from the brook. David! hast thou no fear? Rash youth! is thy unpractised hand able to cope with the mailed champion of Philistia? “I will go and meet him in the name of my God, for I know that the Lord will deliver him into my hand. God will avenge his people, and vindicate his own honor against the insults of his enemies. He who defended me against the lion and the bear will save me from the hand of the blasphemer, and glorify himself this day before the thousands of Israel.” He moves on, invincibly shielded by his faith, and the next moment Goliath is slain with his own sword.
Let us look again at the case of Abraham. God said unto him—“Take now thy son, thine only son Isaac, whom thou lovest, and get thee into the land of Moriah, and offer him there for a burnt offering, upon one of the mountains that I will tell thee of.” Now the enemy assails him, in the persuasive language of natural affection, and carnal reasoning; and every word is like a flaming arrow in the patriarch’s heart:—“Abraham! if thou obey this command, thou wilt disobey thereby many other commands. God hath said—‘Thou shalt not kill;’ and wilt thou shed the blood of thy own child? Canst thou so trample upon the law of God, and all the tender instincts of human nature? How will thy servants regard thee—how will the world look upon thee, after so horrible a deed? What will they think of thy God, when they hear that he has required at thy hand the immolation of thy only son? Will it not bring everlasting dishonor upon his name? And what will become of the Divine promise upon which thy faith is built—that from Isaac’s loins shall spring the Messiah, the hope of the world? Besides, thou wilt certainly break poor old Sarah’s heart; she will never be able to survive the loss, in so dreadful a manner, of her darling boy. If thou hast any feelings of humanity in thy heart, any fear of God before thine eyes, any regard for the glory of his name among men, refrain from that deed of blood!”
Such were the “fiery darts” which “the wicked one” hurled at the good man’s heart, but they fell harmless upon his “shield of faith.” “He staggered not at the promise through unbelief.” “He conferred not with flesh and blood.” He rose up early in the morning, took Isaac and the servants, and set out for the appointed place of sacrifice. He travelled three days toward Moriah, with a settled purpose to cut Isaac’s body in pieces, and shed the blood of his heart upon the altar, and burn it to ashes in the consuming flames. He loved his son as his own soul, but the command of God was dearer to his heart. “And Abraham said unto his young men—Abide ye here with the ass, and I and the lad will go yonder, and worship, and come again to you;” for he firmly believed that God would raise his son from the ashes of the altar, and that they would return together. I see them ascending the hill—O, what an ascent was that! Never was there a walk so sorrowful, till the great Antitype of Isaac ascended the same mountain to “make his soul a sacrifice for sin.” The altar is built, the fire and the wood are placed thereon; and O for words to describe the feelings of both father and son, when Abraham laid hold on Isaac, and took the knife to plunge it into his heart! There is a pause. The patriarch’s arm is stretched aloft, with the instrument of death. God of mercy! is there no help for a father? Earth cannot speak; but there comes a voice from heaven; and O, with what melody it rings through Abraham’s heart!—“Abraham! Abraham! lay not thine hand upon the lad; for now I know that thou fearest God, seeing thou hast not withheld thy son, thine only son, from me.”
There was the triumph of faith. “By faith Abraham, when he was tried, offered up Isaac; and he that had received the promises offered up his only begotten son, of whom it was said—In Isaac shall thy seed be called; accounting that God was able to raise him up even from the dead, from whence also he received him in a figure.” The patriarch’s faith quenched “all the fiery darts of the wicked one,” which were cast at him in this dreadful trial.
The arrows of the orientals were often poisoned at one end, and ignited at the other. It is to this circumstance the apostle alludes in the phrase—“the fiery darts of the wicked,” or the wicked one. Satan has his quiver full of impoisoned and flaming arrows, from which the servants of Christ would be much endangered without “the shield of faith.” He shot one of them at Eve in Paradise, and set the whole world on fire, “and it is set on fire of hell.” He shot an arrow of lust at David, and an arrow of fear at Peter; and both of them were dreadfully wounded in the back. He shot an arrow of covetousness at Judas, and another at Ananias and Sapphira; and having no “shield of faith,” they were smitten, and dropped down into hell.
