Philippians 2:18
For the same cause also do ye joy, and rejoice with me.
The apostle here draws a conclusion and makes a practical application: Wherefore, my beloved, as you have always been obedient, not only in my presence, but now much more in my absence, with fear and trembling work out your own salvation. In accordance with all these considerations that urge Christians to walk and have their conversation, lead their life, in a manner worthy of the Gospel of Jesus Christ, they should continue in their obedience as heretofore. Paul gives them the testimony of having been obedient both when he was present with them and when he was absent. And with the full knowledge of this, with a willingness to pursue the course marked out before them also in the future, he urges them to feel the responsibility of their salvation before God. The salvation, complete and ready for all, they should strive after, make it their business to obtain that. It is true, of course, that salvation is not earned by obedience, it is complete and perfect in Christ. But it may so easily be lost through disobedience, and therefore striving after it with fear and trembling, with the consciousness of inherent weakness and of the dreadful power of temptation, is essential in sanctification. There is here no contradiction of chap. 1:6, where Paul states that he was sure that God would continue the good work to the end. A Christian must be sure that God will give him firmness and confidence and faithfulness, keep him from falling from grace, and he must still be in fear, lest he lose his salvation by his own foolishness. If a Christian looks upon his own flesh, he may well tremble, because it is weak and a willing ally of all enemies; but if a Christian looks to God, he is sure that he will remain in the faith, that he will overcome all the dangers which threaten his faith, that he will finally be victorious over world, flesh, and Satan. This admonition in itself is a means and instrument in the hands of God to keep the Christian in the way of sanctification.
And yet, all depends upon the power of God: For God it is who is working in us both to will and to do for His good pleasure. God works, performs, all good things in His Christians; He urges them on to true obedience. A believer shows his faith by good works. This makes two things necessary, namely, the will to do, the good intention to live as it becometh the Gospel of Jesus Christ, as it is wrought through the Holy Ghost, and then the carrying out of this intention, the changing of will into performance, so that the doing will be properly and effectually performed. And all this on account of God's good pleasure, to carry out His own, gracious will. God really wants to find pleasure in the good works of the believers. And He does find it because of the fact that they are of divine kind and nature, and their works flow out of the divine power in them. In order to be pleased with the works of Christians, He Himself works the good things in them. God gives and donates the will to do good; the regenerated will of man, in the power of God, wills and performs the good thing. The regenerated will of man is controlled, governed, and directed by the will of God. So the believers dare not lose God's assistance in sanctification.
The apostle mentions one point in which their sanctification may find expression: Do everything without murmurings and hesitations. The Christians of Philippi, like the believers of all ages, should do the will of God in all things, do all that God expects of them, even when the flesh is not pleased with it, even when questionings and criticisms want to arise in their hearts. There should be no bickerings and questionings whether this or that is really necessary, whether it is necessary to be so strict in observing the Word of God, whether it really is the Christian's duty to take part in all the enterprises of the Church. The ideal condition of mind is that which simply, sincerely does what is needed.
The result of such behavior is: That you may be irreprehensible and innocent, guiltless children of God in the midst of an iniquitous and perverse generation, among whom you shine as lights in the world, holding up the Word of Life to a glorification for me upon the day of Christ, that I may not have run in vain or labored in vain. The goal of sanctification cannot be reached at one step, it must be reached by a gradual process. Christians must strive more and more to show and prove themselves irreprehensible, without reproof. In the midst of a world steeped in every form of sin and shame they must guard against all contamination, not only to be without reproach on the part of others, but actually innocent of wrong-doing, able to meet all criticism as unjust aspersion. Christians should avoid all offense and be guiltless in this world. There should be a plain and unmistakable distinction between the Christians and the children of this world. They should stand out from the unbelievers, as the light stands out from the surrounding darkness. The entire life of the believers will offer a splendid contrast to all works of darkness and will be a constant reproof to wrong-doers. But not only are the Christians to shine as lights in their good works, in obedience to the will of their heavenly Father and in all subsequent works of faith, but they are also to be the torch-bearers of the Word of Life. The Christians should present to the world, extend before the eyes of the children of this world, the Word of Salvation for their acceptance, that it may serve to enlighten them also unto eternal life. This they do through the works of the divine life in them. Their entire behavior before the world will be a sermon in words and deeds. Their entire life will show what the Word of God is able to accomplish. The mere existence of believers in this world is a missionary factor. And all this, in turn, redounds to the honor of the apostle on the great day of Jesus Christ, the Day of Judgment. He wanted to be able to point to the Christians of Philippi with pride, as a result of his missionary efforts in Christ Jesus. It would show that his efforts had been crowned with success, for the Philippians would present visible, tangible evidence. Note: The Christians of our day may well keep this word in mind in their relation to their pastors, that they may be a credit to the teaching which they have received, both here in time and on the great day of Jesus Christ.
To impress this last fact upon his readers, the apostle adds: But if I be offered upon the sacrifice and service of your faith, I rejoice, and rejoice with you all; in the same way also you rejoice, and rejoice with me. In and by his imprisonment Paul was being poured out like a drink-offering. But at the same time he was offering a sacrifice, a twofold sacrifice. The first sacrifice is that of the Christians' faith. He had succeeded in working faith in their hearts and in strengthening this faith to the present state of growth in sanctification. That was a pleasing sacrifice in the sight of God. The consequence was that the Philippians were now living a sacrifice in service, a true ministry. The apostle assumes that he himself will be offered upon his sacrifice. He may suffer the death of a martyr because of his preaching the Gospel. He knows that he will soon be liberated from the present imprisonment, but that merely places his martyr's death at a somewhat greater distance. The final disposition of his body is even now pretty sure: martyrdom looms up before him. But even should this take place very soon, it cannot hinder the fruits of his labor. He has cause for rejoicing at the faith and Christian life of the Philippians, he is happy in the thought of what has been accomplished. And in the same way his readers should rejoice in their faith, and rejoice with him, as it behooves good Christians, in the love of Christ.
