When John Calvin begins his Institutes, he doesn’t linger in the realm of speculation about God’s essence. He presses us into something far more practical: what it actually means to know God, and what effect that knowledge must have on our lives. In chapter two, he defines what true and genuine religion looks like. It is not abstract philosophy, nor is it outward ceremony. It is a living reality, shaped by the knowledge of who God is, and by our humble submission to Him as He has revealed Himself.
We live in an age much like Calvin’s, in which many people are content to say they “believe in God,” but the God they confess is often no more than a projection of their own preferences. A safer, friendlier version of the Almighty, stripped of His holiness, His justice, and His authority. But Calvin reminds us that piety does not invent its own deity. A pious heart does not imagine a God it would rather deal with, but bows to the God who truly is, the God who defines Himself in His Word, and who makes Himself known in His works. To know God rightly, we must resist the temptation to reshape Him into something more manageable, and instead receive Him as He has revealed Himself.
“The pious mind does not devise for itself any kind of God, but looks alone to the one true God; nor does it feign for him any character it pleases, but is contented to have him in the character in which he manifests himself”.
And what is the effect of knowing this God? It is to bow in reverence, to walk in obedience, to cry to Him in prayer, and to abound in thanksgiving. Calvin reminds us that we cannot think of God without being reminded that we are His workmanship, bound to submit to His authority, owing our life to Him, and obligated to direct all things to His glory. A life that refuses obedience is a life out of joint, corrupted at its core, because God’s will is meant to be the law of our living. True knowledge of God therefore cannot leave us unchanged, it bends the heart in reverence and shapes the life in worship.
“For, until men feel that they owe everything to God, that they are cherished by his paternal care, and that he is the author of all their blessings, so that nought is to be looked for away from him, they will never submit to him in voluntary obedience; nay, unless they place their entire happiness in him, they will never yield up their whole selves to him in truth and sincerity.”
Yet this reverence is not a servile terror. It is a holy awe that binds us nearer. We learn to live before God in a balance of confidence and fear: confidence in His fatherly goodness, and fear of His righteous judgment. The godly person does not shrink from God’s presence, even when faced with His justice, but embraces Him as both Avenger of the wicked and Rewarder of the righteous. Love and reverence run together in the heart of true piety. As Calvin says, even if there were no hell, the child of God would still recoil at the thought of offending Him, simply because he loves Him as Father and honors Him as Lord.
“The effect of our knowledge ought to be, first, to teach us reverence and fear; and, secondly, to induce us, under its guidance and teaching, to ask every good thing from him, and, when it is received, ascribe it to him. True knowledge of God then, should move us to worship, prayer, and thanksgiving.”
This, then, is the essence of true and genuine religion: confidence in God’s goodness coupled with reverent fear of His majesty. Not the empty ceremonies of outward homage, which are abundant in the world, but the rare sincerity of a heart bowed before the living God. Such knowledge of Him leads us to seek all things from His hand, to return thanks for all things received, and to order our lives under His will. Anything less is not true knowledge of God, but only a shadow of Him shaped by our own imaginations. The writer to the Hebrews captures the same spirit: “Let us offer to God acceptable worship, with reverence and awe, for our God is a consuming fire” (Heb. 12:28–29).
True and genuine religion, then, is this: to know the God who has revealed Himself as Creator, Sustainer, Judge, and Father; to seek Him for who He is, not as we would prefer Him to be; to live in confidence of His goodness, and in reverent fear of His majesty. It is to bow the heart in prayer, thanksgiving, obedience, and love.
The question Calvin presses upon us in chapter 2 of The Institute of Christian Religion is simple yet searching: Do we know God as He has revealed Himself? Or have we settled for the safer, smaller version of Him that we prefer? True piety always looks to the real God, the holy and merciful One who rules heaven and earth, who cannot be remade to our liking, but who remakes us by His grace. To know Him in this way is not only the beginning of wisdom, but the beginning of eternal life.
“This is eternal life, that they know you the only true God, and Jesus Christ whom you have sent” (John 17:3)
