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

by John Calvin (compiled by John H. Kromminga)

Bible Text:

Now them that are such we command and exhort by our Lord Jesus Christ, that with quietness they work, and eat their own bread. —II Thessalonians 3:12

Devotional:

The Lord commands every one of us, in all the actions of life, to regard his vocation. For he knows with what great unrest the human mind is inflamed, with what desultory levity it is hurried hither and thither, and how insatiable is its ambition to grasp different things at once.

Therefore, to prevent universal confusion being produced by our folly and temerity, he has appointed to all their particular duties in different spheres of life. And that no one might rashly transgress the limits prescribed, he has styled such spheres of life vocations or callings.

Every individual's line of life, therefore, is, as it were, a post assigned him by the Lord, that he may not wander about in uncertainty all his days. And so necessary is this distinction, that in his sight all our actions are estimated according to it, and often very differently from the sentence of human reason and philosophy.

There is no exploit esteemed more honorable, even among philosophers, than to deliver our country from tyranny; but the voice of the celestial Judge openly condemns the private man who lays violent hands on a tyrant. It is not my design, however, to pause to list examples. It is sufficient if we know that the principle and foundation of right conduct in every case is the vocation of the Lord, and that he who disregards it will never keep the right way in the duties of his station.

He that is in obscurity will lead a private life without discontent, so as not to desert the station in which God has placed him. It will also be no small alleviation of his cares, labors, troubles, and other burdens, when a man owns that in all these things he has God for his guide.

The magistrate will execute his office with greater pleasure, the father of a family will confine himself to his duty with more satisfaction, and all, in their respective spheres of life, will bear and surmount the inconveniences, cares, disappointments, and anxieties which befall them, when they shall be persuaded that every individual has his burden laid upon him by God. Hence also will arise peculiar consolation, since there will be no employment so mean and sordid (provided we follow our vocation) as not to appear truly respectable, and be deemed highly important in the sight of God. —Institutes, III, x, vi


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.
