But we have nothing of the Spirit except through regeneration. Everything, therefore, which we have from nature is flesh.
John CalvinFor though we very truly hear that the kingdom of God will be filled with splendor, joy, happiness and glory, yet when these things are spoken of, they remain utterly remote from our perception, and as it were, wrapped in obscurities, until that day.
John CalvinOn the contrary, therefore, Christ declares that the doctrine of the Gospel, though it is preached to all without exception, cannot be embraced by all, but that a new understanding and a new perception are requisite; and, therefore, that faith does not depend on the will of men, but that it is God who gives it.
John Calvin
