John Calvin on John 10:21

21. These are not the words of a demoniac. It is as if they demanded that men should judge from the fact itself; for the truth, as we have said, is strong enough to maintain itself. And this is the only protection of our faith, that wicked men will never be able to hinder the power and wisdom of God, and his goodness also, “Et aussi sa boute.” from shining in the Gospel.
