At the heart of the Bible is a book full of music called The Psalms. The Psalms are a mixtape collection of songs and prayers written by people as they tried to understand God in the everyday challenges of life. Psalm 1 introduces the mixtape with this question: Who's song is on repeat in your head and your heart? Psalm 1 shows us that there are only two songs you can listen to, so which one are you listening to the most?
