Thine Is My Heart: Devotional Readings from the Writings of John Calvin
by John Calvin (compiled by John H. Kromminga)
He that overcometh, the same shall be clothed in white raiment; and I will not blot out his name out of the book of life, but I will confess his name before my Father, and before his angels. —Revelation 3:5
Therefore we have need to be armed and equipped at every point. But you need not be daunted, seeing that God has promised to equip his own according as they are assaulted by Satan. Only commit yourself to him, distrusting all in yourself, and hope that he only will suffice to sustain you. Further you have to take heed chiefly to two things; first, what the side is you defend, and next, what crown is promised to those who continue steadfast in the Gospel.
The service of God, the boundless grace which he has manifested to us in his Son, and all the glory of his kingdom, are such precious things, that no mortal man ought to think it hard to spend his life in fighting against the base corruptions, whose reign throughout the world tends to bring to naught those blessings.
And then, we know what will be the end of our warfare, and that he who has bought us will never suffer so dear a price as his blood to be lost, if we be but signed with it.
Now we know how he owns as his own, and declares solemnly that he will own at the last day, all those who have confessed him here below. We do not know as yet what he has determined to do concerning you, but there is nothing better for you than to sacrifice your life to him, being ready to part with it whenever he wills, and yet hoping that he will preserve it, in so far as he knows it to be profitable for your salvation.
And although this be difficult to the flesh, yet it is the true happiness of his faithful ones; and you must pray that it may please this gracious God so to imprint it upon your heart that it may never be effaced therefrom. For our part, we also shall pray that he would make you feel his power, and vouchsafe you the full assurance that you are under his keeping; that he bridles the rage of your enemies, and in every way manifests himself as your God and Father. —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."
