Kendrick hopes he ends up in Heaven. He is asking himself if he has done enough. Also a reference to the 1941 film, The Blood Of Jesus in which the setting is heavily African-American, and a main character is introduced to alcohol by a Demon.
Also, in church the Blood of Jesus is red wine. It could also refer to the fear of ending up in Christian “Hell” due to the fact that he is surrounded by sin and has admitted to being a sinner as well. The fear of death in Christian religion is often associated with fear of damnation.
