Something I just read, a reminder to me as to everyone else:

Some have trouble believing that God should take this one act of disobedience so seriously, in what might appear to be a minor matter. But God's law is interconnected. If you disobey one statute (James 2:10), you have violated the whole law. Why? Because sin is of the heart. If you have the kind of heart that would disobey one word of God, you have the kind of heart that would disobey any other word of God. Either you are wholly devoted to serve God or you aren't. And God wants only wholehearted servants.
