Thine Is My Heart: Devotional Readings from the Writings of John Calvin
by John Calvin (compiled by John H. Kromminga)
Arise, O Lord, in thine anger, lift up thyself because of the rage of mine enemies: and awake for me to the judgment that thou hast commanded. My defence is of God, which saveth the upright in heart. —Psalm 7:6, 10
And, indeed, we can never pray in faith unless we attend, in the first place, to what God commands, that our minds may not rashly and at random start aside in desiring more than we are permitted to desire and pray for. David, therefore, in order to pray aright, reposes himself on the word and promise of God; and the import of his exercise is this: Lord, I am not led by ambition, or foolish headstrong passion, or depraved desire, inconsiderately to ask from thee whatever is pleasing to my flesh; but it is the clear light of thy word which directs me, and upon it I securely depend.
Is it not wonderful that David often mingles meditations with his prayers, thereby to inspire himself with true confidence? We may go to God in prayer with great alacrity; but our fervor, if it does not gather new strength, either immediately fails or begins to languish. David, therefore, in order to continue in prayer with the same ardor of devotion and affection with which he commenced, brings to his recollection some of the most common truths of religion, and by this means fosters and invigorates his faith.
He declares that as God saves the upright in heart, he is perfectly safe under his protection. Whence it follows, that he had the testimony of an approving conscience. And as he does not simply say the righteous, but the upright in heart, he appears to have an eye to that inward searching of the heart and reins mentioned in the preceding verse. —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."
