Luke 22:31-38

We learn, from these verses, what a fearful enemy the devil is to believers. We read that “the Lord said, Simon, Simon, Satan hath desired to have you, that he may sift you as wheat.” He was near Christ’s flock, though they saw him not. He was longing to compass their ruin, though they knew it not. The wolf does not crave the blood of the lamb more than the devil desires the destruction of souls.

The personality, activity, and power of the devil are not sufficiently thought of by Christians. This is he who brought sin into the world at the beginning, by tempting Eve. This is he who is described in the book of Job as “going to and fro in the earth, and walking up and down in it.” This is he whom our Lord calls “the prince of this world,” a “murderer,” and a “liar.” This is he whom Peter compares to a “roaring lion, seeking whom he may devour.” This is he whom John speaks of as “the accuser of the brethren.” This is he who is ever working evil in the churches of Christ, catching away good seed from the hearts of hearers, sowing tares amid the wheat, stirring up persecutions, suggesting false doctrines, and fomenting divisions. The world is a snare to the believer. The flesh is a burden and a clog. But there is no enemy so dangerous as that restless, invisible, experienced enemy, the devil.

If we believe the Bible, let us not be ashamed to believe that there is a devil. It is an awful proof of the hardness and blindness of unconverted men, that they can jest and speak lightly of Satan.

If we profess to have any real religion, let us be on our guard against the devil’s devices. The enemy who overthrew David and Peter, and assaulted Christ Himself, is not an enemy to be despised. He is very subtle. He has studied the heart of man for six thousand years. He can approach us under the garb of an “angel of light.” We have need to watch and pray, and put on the whole armour of God. It is a blessed promise, that if we resist him he will flee from us. It is a still more blessed thought, that when the Lord comes, He will bruise Satan under our feet, and bind him in chains. (James 4:7; Rom. 16:20)

We learn, secondly, in these verses, one great secret of a believer’s perseverance in the faith. We read that our Lord said to Peter, “I have prayed for thee that thy faith fail not.” It was owing to Christ’s intercession that Peter did not entirely fall away.

The continued existence of grace in a believer’s heart is a great standing miracle. His enemies are so mighty, and his strength is so small, the world is so full of snares, and his heart is so weak, that it seems at first sight impossible for him to reach heaven. The passage before us explains his safety. He has a mighty Friend at the right hand of God, who ever lives to make intercession for him. There is a watchful Advocate, who is daily pleading for him, seeing all his daily necessities, and obtaining daily supplies of mercy and grace for his soul. His grace never altogether dies, because Christ always lives to intercede. (Heb. 7:25)

If we are true Christians, we shall find it essential to our comfort in religion to have clear views of Christ’s priestly office and intercession. Christ lives, and therefore our faith shall not fail. Let us beware of regarding Jesus only as one who died for us. Let us never forget that He is alive for evermore. Paul bids us specially remember that He is risen again, and is at the right hand of God, and also maketh intercession for us. (Rom. 8:34) The work that He does for His people is not yet over. He is still appearing in the presence of God for them, and doing for their souls what He did for Peter. His present life for them is just as important as His death on the cross eighteen hundred years ago. Christ lives, and therefore true Christians “shall live also.”

We learn, thirdly, from these verses, the duty incumbent on all believers who receive special mercies from Christ. We read that our Lord said to Peter, “When thou art converted strengthen thy brethren.”

It is one of God’s peculiar attributes, that He can bring good out of evil. He can cause the weaknesses and infirmities of some members of His Church to work together for the benefit of the whole body of His people. He can make the fall of a disciple the means of fitting him to be the strengthener and upholder of others.–Have we ever fallen, and by Christ’s mercy been raised to newness of life? Then surely we are just the men who ought to deal gently with our brethren. We should tell them from our own experience what an evil and bitter thing is sin. We should caution them against trifling with temptation. We should warn them against pride, and presumption, and neglect of prayer. We should tell them of Christ’s grace and compassion, if they have fallen. Above all, we should deal with them humbly and meekly, remembering what we ourselves have gone through.

Well would it be for the Church of Christ, if Christians were more ready to good works of this kind! There are only too many believers who in discussion add nothing to their brethren. They seem to have no Saviour to tell of, and no story of grace to report. They chill the hearts of those they meet, rather than warm them. They weaken rather than strengthen. These things ought not so to be. The words of the apostle ought to sink down into our minds, “Having received mercy we faint not. We believe, and therefore we speak.” (2 Cor. 4:1, 13)

We learn, lastly, from these verses, that the servant of Christ ought to use all reasonable means in doing his Master’s work. We read that our Lord said to His disciples, “He that hath a purse, let him take it, and likewise his scrip; and he that hath no sword, let him sell his garment and buy one.”

It is safest to take these remarkable words in a proverbial sense. They apply to the whole period of time between our Lord’s first and second advents. Until our Lord comes again, believers are to make a diligent use of all the faculties which God has implanted in them. They are not to expect miracles to be worked, in order to save them trouble. They are not to expect bread to fall into their mouths, if they will not work for it. They are not to expect difficulties to be surmounted, and enemies to be overcome, if they will not wrestle, and struggle, and take pains. They are to remember that it is “the hand of the diligent which maketh rich.” (Prov. 10:4)

We shall do well to lay to heart our Lord’s words in this place, and to act habitually on the principle which they contain. Let us labour, and toil, and give, and speak, and act, and write for Christ, as if all depended on our exertions. And yet let us never forget that success depends entirely on God’s blessing! To expect success by our own “purse” and “sword” is pride and self-righteousness. But to expect success without the “purse and sword” is presumption and fanaticism. Let us do as Jacob did when he met his brother Esau. He used all innocent means to conciliate and appease him. But when he had done all, he spent all night in prayer. (Gen. 32:1-24)
