Romans 8:2-4

Romans 8:2-4. For the law of the Spirit of life in Christ Jesus hath made me free from the law of sin and death. For what the law could not do, in that it was weak through the flesh, God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh: That the righteousness of the law might be fulfilled in us, who walk not after the flesh but after the Spirit.

None keep the law so well as those who do not hope to be saved by it, but who, renouncing all confidence in their own works, and accepting the righteousness which is of God by faith in Christ Jesus, are moved by gratitude to a height of consecration and a purity of obedience which mere legalism can never know. The child will obey better without desire of reward, than the slave will under the dread of the lash, or in hope of a wage. The most potent motive for holiness is free grace. A dying Saviour is the death of sin. As we have been singing, we strove against its power until we learnt that Christ was the way, and then we conquered it.
