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

by John Calvin (compiled by John H. Kromminga)

Bible Text:

The night is far spent, the day is at hand: let us therefore cast off the works of darkness, and let us put on the armour of light. —Romans 13:12


Although it may be difficult to the weakness of our flesh to continue steadfast when we see no end to our warfare; nay more, see that things grow worse; yet when girt about with the armor which God bestows upon us, we must not fear but that we shall overcome all the devices of Satan.

I call "the armor of God" not merely the promises and holy exhortations by which he strengthens us, but the prayers which are to obtain the strength we need. And therefore, sir, according to your necessity, get by heart what Scripture sets before us, both as to the present condition of Christians, and the miseries to which they must needs be subject, and also as to the happy and desirable issue promised them; and how, moreover, they shall never be forsaken in the time of their need.

I know—long continued maladies being the most harassing—that it is extremely hard for you to languish for such a length of time. But if the enemies of the truth are thus obstinate in their fury, we ought to be ashamed of not being at least equally steadfast in well-doing; and most of all when it concerns the glory of our God and Redeemer, which, of his infinite goodness, he has bound up with our salvation.

And I have no doubt that you put in practice what the Apostle tells you about strengthening the feeble knees and lifting up the hands which hang down. For it cannot be but that the first blows dismay, unless we rouse our virtue to resist temptation. —Correspondence

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.
