It is the sophistry of Satan that the death of Christ brought in grace to take the place of the law. The death of Jesus did not change or annul or lessen in the slightest degree the law of Ten Commandments. That precious grace offered to men through a Saviour's blood establishes the law of God. Since the fall of man, God's moral government and His grace are inseparable. They go hand in hand through all dispensations. “Mercy and truth are met together; righteousness and peace have kissed each other” (Psalm 85:10). FW 30.2
Jesus, our Substitute, consented to bear for man the penalty of the law transgressed. He clothed His divinity with humanity and thus became the Son of man, a Saviour and Redeemer. The very fact of the death of God's dear Son to redeem man shows the immutability of the divine law. How easily, from the transgressor's standpoint, could God have abolished His law, thus providing a way whereby men could be saved and Christ remain in heaven! The doctrine which teaches freedom, through grace, to break the law is a fatal delusion. Every transgressor of God's law is a sinner, and none can be sanctified while living in known sin. FW 30.3
The condescension and agony of God's dear Son were not endured to purchase for man liberty to transgress the Father's law and yet sit down with Christ in His throne. It was that through His merits and the exercise of repentance and faith the most guilty sinner might receive pardon and obtain strength to live a life of obedience. The sinner is not saved in his sins, but from his sins. FW 31.1
