Scripture will ultimately suffice for a saving knowledge of God only when its certainty is founded upon the inward persuasion of the Holy Spirit. Indeed, these human testimonies which exist to confirm it will not be vain if, as secondary aids to our feebleness, they follow that chief and highest testimony. But those who wish to prove to unbelievers that Scripture is the Word of God are acting foolishly, for only by faith can this be known.
John CalvinThe principle exercise which the children of god have is to pray. For in this way they give true proof of their faith.
John CalvinIntegrity is the best of all protectors...we cannot be more secure than when fortified by a good conscience.
John CalvinWherever we find the Word of God surely preached and heard, and the sacraments administered according to the institution of Christ, there, it is not to be doubted, is a church of God.
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.
