The Devil's Logic

Using God's mercy as an excuse to live wickedly is devilish logic that leads to a lost soul.
Thomas Brooks emphasizes that using God's mercy as a justification for sin is the devil's logic, which leads to destruction. He warns that such reasoning is a grave wickedness, as it turns the goodness of God into a license for immorality. Brooks argues that true grace cannot coexist with a lifestyle of sin, and those who adopt this mindset are in grave danger of God's wrath. He contrasts the responses to good and evil, highlighting that to repay good with evil is the most devilish act. Ultimately, he asserts that a genuine Christian cannot live wickedly in light of God's grace.

Text

"Shall we continue in sin, that grace may abound?

God forbid. How shall we who are dead to sin, live

any longer therein?" Romans 6:1, 2

To argue from God's mercy to sinful liberty--is the devil's

logic--and such logicians do ever walk as upon a mine of

gunpowder ready to be blown up! No such soul can ever

avert or avoid the wrath of God. This is wickedness at the

height--for a man to be very bad, because God is very good!

There is not a worse spirit than this in hell. Ah, Lord, does

not wrath, yes, the greatest wrath, lie at this man's door?

Are not the strongest chains of darkness prepared for such

a soul? To sin against mercy is bestial; no, it is worse!

To render good for evil is divine.

To render good for good is human.

To render evil for evil is brutish.

But to render evil for good is devilish!

There is nothing in the world which renders a man more

unlike a Christian, and more like Satan--than to argue

from God's mercy to sinful liberty; from divine goodness

to licentiousness. This is devilish logic, and in whomever

you find it, you may write, 'This soul is lost!'

A man may as truly say, 'the sea burns', or 'the fire cools'

--as that God's free grace and mercy should make a truly

gracious soul to live wickedly.
