The apostle proceeds in these verses to pray for them. He heard that they were good, and he prayed that they might be better. He was constant in this prayer: We do not cease to pray for you. It may be he could hear of them but seldom, but he constantly prayed for them.—And desire that you may be filled with the knowledge, etc. Observe what it is that he begs of God for them,

I. That they might be knowing intelligent Christians: filled with the knowledge of his will, in all wisdom and spiritual understanding. Observe, 1. The knowledge of our duty is the best knowledge. A mere empty notion of the greatest truths is insignificant. Our knowledge of the will of God must be always practical: we must know it, in order to do it. 2. Our knowledge is then a blessing indeed when it is in wisdom, when we know how to apply our general knowledge to our particular occasions, and to suit it to all emergencies. 3. Christians should endeavour to be filled with knowledge; not only to know the will of God, but to know more of it, and to increase in the knowledge of God (as it is Col. 1:10), and to grow in grace, and in the knowledge of our Lord and Saviour, 2 Pet. 3:18.

II. That their conversation might be good. Good knowledge without a good life will not profit. Our understanding is then a spiritual understanding when we exemplify it in our way of living: That you may walk worthy of the Lord unto all pleasing (Col. 1:10), that is, as becomes the relation we stand in to him and the profession we make of him. The agreeableness of our conversation to our religion is pleasing to God as well as to good men. We walk unto all well-pleasing when we walk in all things according to the will of God. Being fruitful in every good work. This is what we should aim at. Good words will not do without good works. We must abound in good works, and in every good work: not in some only, which are more easy, and suitable, and safe, but in all, and every instance of them. There must be a regular uniform regard to all the will of God. And the more fruitful we are in good works the more we shall increase in the knowledge of God. He who doeth his will shall know of the doctrine whether it be of God, John 7:17.

III. That they might be strengthened: Strengthened with all might according to his glorious power (Col. 1:11), fortified against the temptations of Satan and furnished for all their duty. It is a great comfort to us that he who undertakes to give strength to his people is a God of power and of glorious power. Where there is spiritual life there is still need of spiritual strength, strength for all the actions of the spiritual life. To be strengthened is to be furnished by the grace of God for every good work, and fortified by that grace against every evil one: it is to be enabled to do our duty, and still to hold fast our integrity. The blessed Spirit is the author of this strength; for we are strengthened with might by his Spirit in the inward man, Eph. 3:16. The word of God is the means of it, by which he conveys it; and it must be fetched in by prayer. It was in answer to earnest prayer that the apostle obtained sufficient grace. In praying for spiritual strength we are not straitened in the promises, and therefore should not be straitened in our own hopes and desires. Observe, 1. He prayed that they might be strengthened with might: this seems a tautology; but he means, that they might be mightily strengthened, or strengthened with might derived from another. 2. It is with all might. It seems unreasonable that a creature should be strengthened with all might, for that is to make him almighty; but he means, with all that might which we have occasion for, to enable us to discharge our duty or preserve our innocence, that grace which is sufficient for us in all the trials of life and able to help us in time of need. 3. It is according to his glorious power. He means, according to the grace of God: but the grace of God in the hearts of believers is the power of God; and there is a glory in this power; it is an excellent and sufficient power. And the communications of strength are not according to our weakness, to whom the strength is communicated, but according to his power, from whom it is received. When God gives he gives like himself, and when he strengthens he strengthens like himself. 4. The special use of this strength was for suffering work: That you may be strengthened unto all patience and long-suffering with joyfulness. He prays not only that they may be supported under their troubles, but strengthened for them: the reason is there is work to be done even when we are suffering. And those who are strengthened according to his glorious power are strengthened, (1.) To all patience. When patience hath its perfect work (Jas. 1:4) then we are strengthened to all patience—when we not only bear our troubles patiently, but receive them as gifts from God, and are thankful for them. To you it is given to suffer, Phil. 1:29. When we bear our troubles well, though ever so many, and the circumstances of them ever so aggravating, then we bear them with all patience. And the same reason for bearing one trouble will hold for bearing another, if it be a good reason. All patience includes all the kinds of it; not only bearing patience, but waiting patience. (2.) This is even unto long-suffering, that is, drawn out to a great length: not only to bear trouble awhile, but to bear it as long as God pleases to continue it. (3.) It is with joyfulness, to rejoice in tribulation, to take joyfully the spoiling of our goods, and rejoice that we are counted worthy to suffer for his name, to have joy as well as patience in the troubles of life. This we could never do by any strength of our own, but as we are strengthened by the grace of God.
