Who worketh all things. The circumlocution employed in describing the Supreme Being deserves attention. He speaks of Him as the sole agent, and as doing everything according to His own will, so as to leave nothing to be done by man. In no respect, therefore, are men admitted to share in this praise, as if they brought anything of their own. God looks at nothing out of himself to move him to elect them, for the counsel of his own will is the only and actual cause of their election. This may enable us to refute the error, or rather the madness, of those who, whenever they are unable to discover the reason of God’s works, exclaim loudly against his design. 
Albert Barnes notes the following about God's counsel:
After the counsel of his own will. Not by consulting his creatures, or conforming to their views, but by his own views of what is proper and right. We are not to suppose that this is by mere will, as if it were arbitrary, or that he determines anything without good reason. The meaning is, that his purpose is determined by what he views to be right, and without consulting his creatures or conforming to their views. His dealings often seem to us to be arbitrary. We are incapable of perceiving the reasons of what he does. He makes those his friends who we should have supposed would have been the last to have become Christians. He leaves those who seem to us to be on the borders of the kingdom, and they remain unmoved and uneffected. But we are not thence to suppose that he is arbitrary. In every instance, we are to believe that there is a good reason for what he does, and one which we may be permitted yet to see, and in which we shall wholly acquiesce. The phrase "counsel of his own will" is remarkable. It is designed to express in the strongest manner the fact that it is not by human counsel or advice. The word "counsel"--βουλη--means, a council or senate; then a determination, purpose, or decree. See Rob. Lex. Here it means that his determination was formed by his own will, and not by human reasoning. Still, his will in the case may not have been arbitrary. When it is said of man that he forms his own purposes, and acts according to his own will, we are not to infer that he acts without reason, he may have the highest and best reasons for what he does, but he does not choose to make them known to others, or to consult others. So it may be of God, and so we should presume it to be. It may be added, that we ought to have such confidence in him as to believe that he will do all things well. The best possible evidence that anything is done in perfect wisdom and goodness, is the fact that God does it. When we have ascertained that, we should be satisfied that all is right.
