Men are indeed to be taught that the favour of God is offered, without exception, to all who ask it; but since those only begin to ask whom heaven by grace inspires, even this minute portion of praise must not be withheld from Him. It is the privilege of the elect to be regenerated by the Spirit of God, and then placed under His guidance and government.
John CalvinNearly all the wisdom we possess, that is to say, true and sound wisdom, consists of two parts: the knowledge of God and of ourselves.
John CalvinScripture 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 CalvinTo search for wisdom apart from Christ means not simply foolhardiness but utter insanity.
