John Calvin: His own words on certainty

For those who think doubting and having questions is wrong… should bone up on Calvin more.

Calvin on certainty:

Unbelief is so deeply rooted in our hearts, and we are so inclined to it, that not without hard struggle is each one able to persuade himself of what all confess with the mouth: namely, that God is faithful.

While we teach that faith ought to be certain and assured, we cannot imagine any certainty that is not tinged with doubt, or any assurance that is not assailed by some anxiety. On the other hand, we say that believers are in perpetual conflict with their own unbelief. • Inst. III.ii.15, 17.

Sounds rather Arminian of him.
