Arminianism is enmity against God.

All seem to agree about this, that the great end of all the Lord's counsels and decrees is his own glory, to be manifested on men and angels; and that this must be first in his mind; not that there is first or last with him, but to speak after the manner of men. If he had many thoughts, as we have, this would be his first thought; and in this one purpose this end is chiefly aimed at, and all other things are by the Lord's counsel subordinate to this, as means to compass that. But as concerning the order of these means, and consequently of his majesty's purpose about them, men, by examining his majesty according to the creature's rules, or according to sense, bring him down far below his own infinite greatness. Some conceive that that was first, as it were, in his mind which is first done. Looking upon the execution of his purpose in the works of his power, they imagine, that as he first created man righteous, so this was his first thought concerning man, to create man for the glory of his goodness and power, without any particular determination as yet of his end. And I conceive, this is the thought of the multitude of people. They think God was disappointed in his work, when they hear he created such a glorious creature that is now become so miserable. They cannot believe that his majesty had all this sin and misery determined with him when he purposed to create him, but look upon the emergent of man's fall into sin and misery as a surprisal of his majesty; - as if he had meant another thing in creating him, and so was, upon this occasion of man's sin, driven to a new consultation about the helping of the business, and making the best out of it that might be. Thus 'through wisdom' the world knows not God. They think God altogether like themselves, and so liken him to the builder of a house, who set nothing before him in doing so, but to build it after that manner for his own ends; but then being surprised with the fall and ruin of it, takes a new advisement, and builds it up again upon another and a surer foundation. But because they cannot say, that God takes any new advisements in time, but must confess that all his counsels are everlasting concerning all the works of his hands, therefore they bring in foreknowledge to smooth their irreligious conceit of God; as if the Lord, upon his purpose of creating man, had foreseen what should befall him, and so purposed to permit it to be so, that out of it he might erect some glorious fabric of mercy and justice upon the ruins of man. And that little or nothing may be left to the absolute sovereign will of God, to which the Scripture ascribes all things, they must again imagine, that upon his purpose of sending Christ to save sinners, he is yet undetermined about the particular end of particular men, but watches on the tower of foreknowledge to espy what they will do, whether men will believe on his Son or not, whether they will persevere in faith or not; and according to his observation of their doings, so he applies his own will to carve out their reward or portion of life or death. These are even the thoughts which are inbred in your breasts by nature. That which the learned call Arminianism is nothing else but the carnal reason of men's hearts, which is enmity to God. It is that very disputation which Paul in this chapter exclaims against, 'Who art thou, O man, that disputest?'
