Meaning of "Best Friend" by Johnny Cash

The lyrics in "Best Friend" reflect on the wisdom passed down from an old man to the speaker, emphasizing the idea that individuals are responsible for their own lives and destinies.

The line "God is the best friend that you've ever had" suggests that finding solace in faith can provide comfort and guidance in difficult times. Overall, the song serves as a reflection on the importance of living a meaningful life and making positive choices while acknowledging the inevitability of death.
