John Calvin Put Milk Where?

Remember that John Calvin is that famed great theologian who is oft derided for his love of God's sovereign rule over creation. It's important to remember the great comfort that Calvin recognized the Scriptures gave for us in the midst of suffering. That's why the same man who wrote this about his kidney stones:
"[They] gave me exquisite pain. ... At length not without the most painful strainings I ejected a calculus which in some degree mitigated my sufferings, but such was its size that it lacerated the urinary canal and a copious discharge of blood followed. This hemorrhage could only be arrested by an injection of milk through a syringe." (from John Piper's biography here)
Could write this about God's sovereignty in sending the disciples out on a boat in the middle of a storm:
Matthew 14:22. And immediately Jesus constrained his disciples They must have been constrained; for they would never, of their own accord, have left him, and gone to the other side. Now in this they testify their great veneration for him, when, contrary to their own opinions, they yield to his command and obey it. And, indeed, it had an appearance of absurdity, that he should remain alone in a desert place, when night was approaching. But so much the greater commendation is due to the submissiveness of those who set a higher value on the authority of their heavenly teacher than on all that could be pleaded on the other side. And, indeed, we do not truly and perfectly obey God, unless we implicitly follow whatever he commands, though our feelings may be opposed to it. There is always the best reason, no doubt, for every thing that God does; but he often conceals it from us for a time, in order to instruct us not to be wise in ourselves, but to depend entirely on the expression of his will. And thus Christ constrained his disciples to cross over, in order to train them to that rule of obedience which I have mentioned; though there cannot be a doubt that he intended to prepare the way for the miracle which will immediately come under our consideration.

23. He went up into a mountain alone. It is probable that the Son of God, who was fully aware of the tempest that was coming on, did not neglect the safety of his disciples in his prayers; and yet we naturally wonder that he did not rather prevent the danger than employ himself in prayer. But in discharging all the parts of his office as Mediator, he showed himself to be God and man, and exhibited proofs of both natures, as opportunities occurred. Though he had all things at his disposal, he showed himself to be a man by praying; and this he did not hypocritically, but manifested sincere and human affection towards us. In this manner his divine majesty was for a time concealed, but was afterwards displayed at the proper time.

So, the question remains. Can you and I rejoice in God's Sovereignty even when he sends us kidney stones?
