Grace and Truth

In my reading this morning, this little paragraph by John MacArthur jumped off the page at me: "We have no business preaching grace to people who do not understand the implications of God's law. It is meaningless to expound on grace to someone who does not know the divine demand for righteousness. Those who do not even sense their own guilt cannot possibly comprehend God's mercy. You cannot preach a gospel of grace to someone who has not heard that God requires obedience and punishes disobedience."
