By their acceptance of Arminian confessions as viable expressions of Christian conviction, they show that the Arminian heresy is actually the starting point of their own belief. Because nothing can be more abusive to the lives of God's flock than to flatter them with a false assurance, allowing them to feed upon the insidious poison of the false gospel. For, to borrow again the analogy of food, the false gospel is not the spiritual equivalent of rice and water, but rat poison. If I allow by my tolerance of Arminian confessions those who express those confessions to think all is well with their souls while they are convinced of the evil assertion of human sovereignty represented therein and so feed on it, I am treating their condition as though it were not serious and speaking peace to their souls when I should, like a true shepherd, be seeking to warn them and to bind their wound with the blessed truth of God's pure grace. Jeremiah the addressed just such a situation as he prophesied to the people of Jerusalem.
False assumptions yield false assurance.
Arminianism, as we have said, is based on the falsehood of human sovereignty. It wickedly assumes that man is the ultimate reason for his own salvation, and that God depends on man to secure a salvation that without sovereign man's consent and effort in maintaining it, would be no salvation. Believing it leads to a false assurance of peace and favor with God, for Arminianism is actually an affront to God. Therefore, so long as the true gospel is presented as an optional preference for those two wish to have a greater degree of biblical consistency, it is dishonored and sinfully misrepresented, for the false and dangerous notion of human sovereignty is allowed, to the harm of the people of God. God's saving truth is not optional, but absolutely essential, and can never be held as a preference, but as a matter of necessity.
