From evangelicalarminians.org:

Arminians have a high view of God’s sovereignty, contrary to the caricatures spread of us to the contrary. As a matter of fact, we think Arminians hold to a higher view of God’s sovereignty than do Calvinists, as I was reminded from my Arminian brother, Johnathan Pritchett. The reason the Arminian view of God’s sovereignty is considered higher than that of Calvinism is due to the following. For an omnipotent God, strictly controlling all people is easy and effortless. Like moving chess pieces on a chessboard, the movements are swift and carefree. The pieces move wherever the overseer places them without the slightest challenge whatsoever.

But when considering the individuality of each created being, coupled with their complexities and, at times, irrationality, to say nothing of their will, God is still able to work “all things according to his counsel and will” (Eph. 1:11), and to do so without controlling and manipulating His creatures (because human beings are not chess pieces or objects). You can make an object obey you by controlling it. But wooing a human being to love and obey you is another matter entirely — one which requires honesty, vulnerability, and relationship.
