Thine Is My Heart: Devotional Readings from the Writings of John Calvin

by John Calvin (compiled by John H. Kromminga)

Bible Text:

O Zion, that bringest good tidings, get thee up into the high mountain; O Jerusalem, that bringest good tidings, lift up thy voice with strength; lift it up, be not afraid; say unto the cities of Judah, Behold your God! —Isaiah 40:9

Devotional:

"That bringest tidings." Yet we ought carefully to observe this commendation which God bestows on his Church, that it may not be without a clear mark of distinction; for an assembly in which the preaching of heavenly doctrine is not heard does not deserve to be reckoned a Church. In this sense also, Paul calls it (I Tim. 3:15) "the pillar and ground of truth"; for although God might have governed us by himself, and without the agency of men, yet he has assigned this office to his Church, and has committed to it the invaluable treasure of his Word. For the same reason it will be called in another passage, "the mother of all believers" (Isa. 54:1; Gal.4:26). Hence it follows that nothing is more absurd and wicked than for dumb idols to boast of the name of the Church.

We are likewise taught that the Church has not been instructed of God in order that she may keep her knowledge hidden within herself, but that she may publish what she has learned.

Besides, he commands that grace shall be freely and boldly proclaimed, that prophets and teachers may not speak with timidity, as if it were a doubtful matter, but may show that they are fully convinced of the certainty of those things which they promise, because they know well that "God, who cannot lie" (Titus 1:2) is the Author of them. He enjoins the witnesses of his grace to proceed from Zion, that they may fill with joy the whole of Judea. —Commentaries


John Calvin was the premier theologian of the Reformation, but also a pious and godly Christian pastor who endeavored throughout his life to point men and women to Christ. We are grateful to Reformation Heritage Books for permission to use John Calvin's Thine Is My Heart as our daily devotional for 2013 on the OPC Web site. You can currently obtain a printed copy of that book from Reformation Heritage Books.

Dr. Joel Beeke, who is editorial director of Reformation Heritage Books, has this to say:

"Calvin shows us the piety of a Reformed theologian who speaks from the heart. Having tasted the goodness and grace of God in Jesus Christ, he pursued piety by seeking to know and do God’s will every day. He communed with Christ, practicing repentance, self-denial, and cross-bearing. Moreover, his theology worked itself out in heart-felt, Christ-honoring piety. The selections of this devotional bear this out, and hopefully will be used by God to direct pious hearts in our own day."

These devotional readings from John Calvin were compiled by John H. Kromminga. Be sure to read his "Introduction" to John Calvin's Thine Is My Heart.
