VERSE 16. This I say then, Walk in the Spirit, and ye shall not fulfill the lust of the flesh. "I have not forgotten what I told you about faith in the first part of my letter. Because I exhort you to mutual love you are not to think that I have gone back on my teaching of justification by faith alone. I am still of the same opinion. To remove every possibility for misunderstanding I have added this explanatory note: 'Walk in the Spirit, and ye shall not fulfill the lust of the flesh.'" With this verse Paul explains how he wants this sentence to be understood: By love serve one another. When I bid you to love one another, this is what I mean and require, 'Walk in the Spirit.' I know very well you will not fulfill the Law, because you are sinners as long as you live. Nevertheless, you should endeavor to walk in the spirit, i.e., fight against the flesh and follow the leads of the Holy Ghost." It is quite apparent that Paul had not forgotten the doctrine of justification, for in bidding the Galatians to walk in the Spirit he at the same time denies that good works can justify. "When I speak of the fulfilling of the Law I do not mean to say that you are justified by the Law. All I mean to say is that you should take the Spirit for your guide and resist the flesh. That is the most you shall ever be able to do. Obey the Spirit and fight against the flesh." VERSE 16. And ye shall not fulfill the lust of the flesh. The lust of the flesh is not altogether extinct in us. It rises up again and again and wrestles with the Spirit. No flesh, not even that of the true believer, is so completely under the influence of the Spirit that it will not bite or devour, or at least neglect, the commandment of love. At the slightest provocation it flares up, demands to be revenged, and hates a neighbor like an enemy, or at least does not love him as much as he ought to be loved. Therefore the Apostle establishes this rule of love for the believers. Serve one another in love. Bear the infirmities of your brother. Forgive one another. Without such bearing and forbearing, giving and forgiving, there can be no unity because to give and to take offense are unavoidably human. Whenever you are angry with your brother for any cause, repress your violent emotions through the Spirit. Bear with his weakness and love him. He does not cease to be your neighbor or brother because he offended you. On the contrary, he now more than ever before requires your loving attention. The scholastics take the lust of the flesh to mean carnal lust. True, believers too are tempted with carnal lust. Even the married are not immune to carnal lusts. Men set little value upon that which they have and covet what they have not, as the poet says: "The things most forbidden we always desire, And things most denied we seek to acquire." I do not deny that the lust of the flesh includes carnal lust. But it takes in more. It takes in all the corrupt desires with which the believers are more or less infected, as pride, hatred, covetousness, impatience. Later on Paul enumerates among the works of the flesh even idolatry and heresy. The apostle's meaning is clear. "I want you to love one another. But you do not do it. In fact you cannot do it, because of your flesh. Hence we cannot be justified by deeds of love. Do not for a moment think that I am reversing myself on my stand concerning faith. Faith and hope must continue. By faith we are justified, by hope we endure to the end. In addition we serve each other in love because true faith is not idle. Our love, however, is faulty. In bidding you to walk in the Spirit I indicate to you that our love is not sufficient to justify us. Neither do I demand that you should get rid of the flesh, but that you should control and subdue it."
