God is sovereign. He does whatever he wants. What does he want? He wants to keep his word. He wants to fulfill his promises regarding healing, prophecy, and all kinds of miracles.

The Christian cessationist is a hypocrite, but the greatest hypocrite is the Calvinist cessationist. He claims to believe in the sovereignty of God, but refuses to let God do what he wants.

Thus all his condemnations against the Arminians return to himself, and with much greater force due to his hypocrisy. No open theist, no atheist, and even no Satanist is as much a hypocrite as the cessationist.

God is not a sovereign liar or a sovereign loser. He is eager to keep his word, and because he is sovereign, he is also able to do it.
