(19) According to the working of his mighty power.--More correctly (see margin), the working of the might of His strength. The word "power" is a general word for force, which may be latent, and, in fact, often describes force which is latent, in contradistinction to the word here used for working or energy. St. Paul, therefore, adds that this power of God is not latent; it actually works "according to," that is, up to the full measure of "the might of the strength" of God--of that strength which is a part of His nature. The whole phrase forms a glorious climax, in which the Apostle accumulates words ever stronger and stronger to approach to the description of the omnipotence of the Spirit. It is a "force of exceeding greatness;" it is an ever energetic force; its only measure is the immeasurable might of the divine nature. (Comp. Ephesians 3:7; Philippians 3:21; Colossians 1:29; Colossians 2:12.)

Verse 19. - And what the exceeding greatness of his power toward us who believe. A new object of knowledge is here brought forward - knowledge of a power which works in us - a great power, a Divine power, a power surpassingly great. The whole energy of the Divine Being is turned on to our feeble, languid nature, vivifying, purifying, and transforming it, making it wonderfully active where all was feebleness before, as the turning on of steam suddenly wakens up a whole mass of inert machinery. When we think of the glory of the inheritance, we feel unfit for it; our narrow hearts, cold temperaments, feeble and dislocated faculties, how can they ever be right? Our fear is removed when we think of the greatness of the Divine power that works in us - God's power to transform us so that, "though we have lien among the pots, we shall be as the wings of a dove covered with silver, and her feathers with yellow gold." According to the working of his mighty power. We are now furnished with a standard and sample of the mighty power which energizes in believers are referred to one of its grandest achievements, in order to elevate our conceptions of what it is capable of effecting in us. In the prophets we find a similar encouragement for God's people, in sublime descriptions of the almighty power of him who was working in them and for them (Isaiah 40:21, etc.; Isaiah 45:7, etc.).

1:15-23 God has laid up spiritual blessings for us in his Son the Lord Jesus; but requires us to draw them out and fetch them in by prayer. Even the best Christians need to be prayed for: and while we hear of the welfare of Christian friends, we should pray for them. Even true believers greatly want heavenly wisdom. Are not the best of us unwilling to come under God's yoke, though there is no other way to find rest for the soul? Do we not for a little pleasure often part with our peace? And if we dispute less, and prayed more with and for each other, we should daily see more and more what is the hope of our calling, and the riches of the Divine glory in this inheritance. It is desirable to feel the mighty power of Divine grace, beginning and carrying on the work of faith in our souls. But it is difficult to bring a soul to believe fully in Christ, and to venture its all, and the hope of eternal life, upon his righteousness. Nothing less than Almighty power will work this in us. Here is signified that it is Christ the Saviour, who supplies all the necessities of those who trust in him, and gives them all blessings in the richest abundance. And by being partakers of Christ himself, we come to be filled with the fulness of grace and glory in him. How then do those forget themselves who seek for righteousness out of him! This teaches us to come to Christ. And did we know what we are called to, and what we might find in him, surely we should come and be suitors to him. When feeling our weakness and the power of our enemies, we most perceive the greatness of that mighty power which effects the conversion of the believer, and is engaged to perfect his salvation. Surely this will constrain us by love to live to our Redeemer's glory.And what is the exceeding greatness of his power to us-ward who believe,.... The objects of the divine power here intended, are believers in Christ; which distinguishes this power from that which was put forth in creation, and from that which will be displayed in the resurrection of the dead, and from the power of divine wrath, which will appear in the damnation of sinners; and shows, that this power is that which is exerted in the implantation of faith, and in the continuance of it, and in the finishing of that work; and that this is a great power, an exceeding great one, a super eminent one; which is attended with energy and efficacy, and is irresistible and insuperable: the greatness of this power as displayed in the work of conversion and faith appears, if it be considered what the work itself is called, a creation, a resurrection from the dead, a regeneration, and a transformation of the man into another man, which must needs require almighty power; as well as what is then done, some things are removed, Satan is dispossessed, the stony heart is taken away, the enmity is slain, the old man is put down from his throne, and put off with his deeds; and there are some things wrought, Christ is formed in the soul, his grace is implanted, his image is stamped on, a new heart is given, and principles of light and life, of grace and holiness are put; the understanding is enlightened, the will is subdued, the affections are set on other objects, and the mind and conscience are cleansed and purified; and the means of this are the ministers, and ministry of the word, which are weak, foolish, and contemptible, in the eyes of men; to which may be added, the opposition made both from within and from without, from a sinful heart, a tempting devil, and an ensnaring, reproaching, and persecuting world: so that this work of faith cannot be ascribed to anything short of the exceeding greatness of divine power; and which is seen in supporting faith when it is wrought, under great discouragements; in delivering believers out of divers temptations; in assisting them to discharge their duty, and in their final perseverance: and to increase the idea of this power it is added,

according to the working of his mighty power, or "according to the energy of the might of his power": the strength of his power, in all the mighty energy of it, is exerted towards and upon believers; and which they should know, own, and acknowledge, to the glory of the grace of God: and this is in proportion, and agreeably to that power.
