R.C. Sproul

"By studying or meditating on the law of God, we attend the school of righteousness. We learn what pleases God and what offends Him. The moral law that God reveals in Scripture is always binding upon us. Our redemption is from the curse of God's law, not from our duty to obey it. We are justified, not because of our obedience to the law, but in order that we may become obedient to God's law. To love Christ is to keep His commandments. To love God is to obey His law."
