first of all...I think the lines are "Though I am wretched, I am not faithless" instead of "go on, wretch it out, am i faithless?"

This song really speaks to me after I read the Scarlet Letter where the main character has committed adultery and is forced to wear a scarlet letter "A" on her dress the rest of her life. The whole book is about her constant torment and turmoil. She believes the "A" is penance but she finds that she is not rid of her guilt. In the song, during the part with the message, he is saying that the greatest sin is not accepting the saving grace of Jesus Christ and leaving behind the sin. God has already forgiven the sinner, but it is our job to accept that forgiveness and leave the sin behind.
