What I think is the most important thing to learn about any instrument is the basics of music. Learn your ABCs before you write a Hemingway novel.
Sin is what you do when your heart is not satisfied with God. No one sins out of duty. We sin because it holds out some promise of happiness. That promise enslaves us until we believe that God is more to be desired than life itself (Psalm 63:3). Which means that the power of sin's promise is broken by the power of God's.
