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

by John Calvin (compiled by John H. Kromminga)

Bible Text:

Owe no man any thing, but to love one another: for he that loveth another hath fulfilled the law. —Romans 13:8

Devotional:

The third use of the law, which is the principal one, and which is more nearly connected with the proper end of it, relates to the faithful, in whose hearts the Spirit of God already lives and reigns. For although the law is inscribed and engraven on their hearts by the finger of God—that is, although they are so excited and animated in the direction of the Spirit that they desire to obey God—yet they derive a twofold advantage from the law.

For they find it an excellent instrument to give them, from day to day, a better and more certain understanding of the Divine will to which they aspire, and to confirm them in the knowledge of it. As, though a servant be already influenced by the strongest desire of gaining the approbation of his master, yet it is necessary for him carefully to inquire and observe the orders of his master, in order to conform to them.

Nor let anyone of us exempt himself from this necessity; for no man has already acquired so much wisdom, that he could not by the daily instruction of the law make new advances into a purer knowledge of the Divine will.

In the next place, as we need not only instruction, but also exhortation, the servant of God will derive this further advantage from the law; by frequent meditation on it he will be excited to obedience, he will be confirmed in it, and restrained from the slippery path of transgression.

For in this manner should the saints stimulate themselves, because with whatever alacrity they labor for the righteousness of God according to the Spirit, yet they are always burdened with the indolence of the flesh, which prevents their proceeding with due promptitude. To this flesh the law serves as a whip, urging it, like a dull and tardy animal, forward to its work; and even to the spiritual man, who is not yet delivered from the burden of the flesh, it will be a perpetual spur, that will not permit him to loiter. —Institutes, II, vii, xii


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.
