Only be strong and very courageous; be careful to do according to all the law which Moses My servant commanded you; do not turn from it to the right or to the left, so that you may have success wherever you go. This book of the law shall not depart from your mouth, but you shall meditate on it day and night, so that you may be careful to do according to all that is written in it; for then you will make your way prosperous, and then you will have success. Have I not commanded you? Be strong and courageous! Do not tremble or be dismayed, for the Lord your God is with you wherever you go.

But don’t just listen to God’s word. You must do what it says. Otherwise, you are only fooling yourselves. For if you listen to the word and don’t obey, it is like glancing at your face in a mirror. You see yourself, walk away, and forget what you look like. But if you look carefully into the perfect law that sets you free, and if you do what it says and don’t forget what you heard, then God will bless you for doing it.
