Yesterday at Redeemer I quoted Stephen Charnock from his classic, The Existence and Attributes of God, arguing that all sin has its roots in a form of atheism. Charnock wrote,
All sin is founded in a secret atheism. Atheism is the spirit of every sin; all the floods of impieties in the world break in at the gate of a secret atheism, and though several sins may disagree with one another, yet, like Herod and Pilate against Christ, they join hand in hand against the interest of God.
All the wicked inclinations in the heart, and struggling motions, secret repinings, self-applauding confidences in our own wisdom, strength, &c., envy, ambition, revenge, are sparks from this latent fire [of secret atheism]; the language of every one of these is, I would be a Lord to myself, and would not have a God superior to me...
Every sin is a kind of cursing God in the heart; an aim at the destruction of the being of God; not actually, but virtually; not in the intention of every sinner, but in the nature of every sin.
When we sin we are not disbelieving the existence of God, we are disbelieving God himself. In that moment we do not believe God is worth our love, honor, obedience, and worship. We are acting as if God were dead, or that we wish he were. This is the blasphemy of sin.
