I know of a few musicians that have fallen in my days. I have also known some people who's faith in the Church and the Christian walk that was shaken as a result.
Thankfully I have never put musicians on a level as Jesus Christ, it's sad some do. While I respect them, I know they are human.
I just say go to church and serve the Lord. My worship leader could fail tomorrow, it would not shake my faith. I am in a relationship with Jesus Christ. These people had a relationship with religion, or perhaps even personal fame.
