Enmity against God is the doctrine that the fallen, unregenerate heart is not merely indifferent or neutral toward God, but actively hostile to Him—an enemy in its very disposition, opposed to His rule, His law, and His person. Paul states it without softening: the carnal mind is enmity against God, for it is not subject to the law of God, neither indeed can be. This is the most penetrating diagnosis of the natural state. It is not that fallen men merely lack a relationship with God which they would gladly accept if offered, nor that they are spiritually asleep and need only awakening; it is that they are at war with God, alienated and enemies in their mind by wicked works, hating the light and refusing to come to it lest their deeds be reproved. This enmity may be open and blasphemous, or it may be hidden beneath religious respectability and outward morality, but it is real in every unconverted heart, surfacing the moment God’s true claims press upon the will. The doctrine demolishes the sentimental notion that all men are secretly seeking God and need only a gentle invitation; the truth is that none seeks after God, and that men must be reconciled to Him precisely because they are His enemies. Herein the wonder of the gospel shines: while we were yet enemies, we were reconciled to God by the death of His Son. Reconciliation presupposes hostility; God did not negotiate with neutral parties but made peace with rebels, conquering their enmity by sovereign grace, slaying the hostility through the cross, and turning enemies into sons.
