The following texts also show it: "Thou shalt call His name Jesus; for He shall save His people from their sins." Matt. 1:21.
Since sin is the transgression of a law, it is evident that to save onefrom sin, or from the transgression of the law, is the same thing as making and keeping him obedient to the law.
Therefore the gospel is the revelation of the power of God to work righteousness in men—to manifest righteousness in their lives.
The gospel, therefore, proclaims God’s perfect law, and contemplates nothing less than perfect obedience to it.
Let it not be overlooked that it requires no less a power than the power of God, to exhibit righteous acts in the lives of men. Man’s power is wholly inadequate. This is easily seen when we recognize what the righteousness is, that is to be revealed in the life. The text says that it is "the righteousness of God."
The righteousness of God is set forth in His law. Isa. 51:6, 7."
