Obadiah Sedgwick provides a graphic illustration of the insincerity involved in the Arminian notion of universal will (Bowels of Tender Mercy, 299):
Those who insist that the well-meant offer must include a desire in God for the salvation of all men effectively change the nature of the offer and bring in an element of insincerity.
Can any man reasonably make Christ thus to express himself? "Father, thou didst seriously will the salvation of all alike, and so did I myself, and nothing is wanting on thy part, nor yet on mine, that all sinners might enjoy the same. Nevertheless I thank thee who didst thus love all alike, that thou hast hid the doctrine and knowledge of this universal salvation from the wise and prudent." Do you call this an equal love to all!
