“What shall we say then? Is the law sin? God forbid. No, I had not known sin, but by the law: for I had not known lust, except the law had said, You shall not covet.” Romans 7:7.

Paul says that “as touching the law”—as far as outward acts were concerned—he was “blameless,” but when the spiritual character of the law was discerned, when he looked into the holy mirror, he saw himself a sinner. Judged by a human standard, he had abstained from sin, but when he looked into the depths of God’s law, and saw himself as God saw him, he bowed in humiliation, and confessed his guilt. –Ye Shall Receive Power, p. 289.

Jesus takes up the commandments separately, and explains the depth and breadth of their requirement. Instead of removing one jot of their force, He shows how far-reaching their principles are, and exposes the fatal mistake of the Jews in their outward show of obedience. He declares that by the evil thought or the lustful look the law of God is transgressed. One who becomes a party to the least injustice is breaking the law and degrading his own moral nature. Murder first exists in the mind. He who gives hatred a place in his heart is setting his feet in the path of the murderer, and his offerings are abhorrent to God.  …

 It is true there is an indignation that is justifiable, even in the followers of Christ. When they see that God is dishonored, and His service brought into disrepute, when they see the innocent oppressed, a righteous indignation stirs the soul. Such anger, born of sensitive morals, is not a sin. But those who at any supposed provocation feel at liberty to indulge anger or resentment are opening the heart to Satan. Bitterness and animosity must be banished from the soul if we would be in harmony with heaven. –The Desire of Ages, p. 310
