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

by John Calvin (compiled by John H. Kromminga)

Bible Text:

And of his fulness have all we received and grace for grace. —John 1:16

Devotional:

"And of his fulness." True indeed, the fountain of life, righteousness, virtue, and wisdom, is with God, but to us it is a hidden and inaccessible fountain.

But an abundance of those things is exhibited to us in Christ, that we may be permitted to have recourse to him; for he is ready to flow to us, provided that we open up a channel by faith. He declares in general that out of Christ we ought not to seek anything good, though this sentence consists of several clauses.

First, he shows that we are all utterly destitute and empty of spiritual blessings; for the abundance which exists in Christ is intended to supply our deficiency, to relieve our poverty, to satisfy our hunger and thirst.

Secondly, he warns us that, as soon as we have departed from Christ, it is in vain for us to seek a single drop of happiness, because God has determined that whatever is good shall reside in him alone. Accordingly, we shall find angels and men to be dry, heaven to be empty, the earth to be unproductive, and in short all things to be of no value, if we wish to be partakers of the gifts of God in any other way than through Christ.

Thirdly, he assures us that we shall have no reason to fear the want of any thing, provided that we draw from the fulness of Christ, which is in every respect so complete, that we shall experience it to be a truly inexhaustible fountain; and John classes himself with the rest, not for the sake of modesty, but to make it more evident that no man whatever is excepted. —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.
