Now unto him that is able to do exceeding abundantly above all that we ask or think, according to the power that worketh in us, Now unto him - Having finished his short, but most wonderfully comprehensive and energetic prayer, the apostle brings in his doxology, giving praise to Him from whom all blessings come, and to whom all thanks are due.
That is able to do exceeding abundantly - It is impossible to express the full meaning of these words, God is omnipotent, therefore he is able to do all things, and able to do ὑπερ εκ περισσου, superabundantly above the greatest abundance. And who can doubt this, who has any rational or Scriptural views of his power or his love?
All that we ask or think - We can ask every good of which we have heard, every good which God has promised in his word; and we can think of, or imagine, goods and blessings beyond all that we have either read of or seen: yea, we can imagine good things to which it is impossible for us to give a name; we can go beyond the limits of all human descriptions; we can imagine more than even God has specified in his word; and can feel no bounds to our imagination of good, but impossibility and eternity: and after all, God is able to do more for us than we can ask or think; and his ability here is so necessarily connected with his willingness, that the one indisputably implies the other; for, of what consequence would it be to tell the Church of God that he had power to do so and so, if there were not implied an assurance that he will do what his power can, and what the soul of man needs to have done?
According to the power that worketh in us - All that he can do, and all that he has promised to do, will be done according to what he has done, by that power of the holy Ghost την ενεργουμενην, which worketh strongly in us - acts with energy in our hearts, expelling evil, purifying and refining the affections and desires, and implanting good.
