Fornicators "Will Not Inherit the Kingdom of God": Is I Corinthians addressed to believers or unbelievers when he refers to the fornicators not inheriting the Kingdom of God? [I Corinthians 6:9-10, I Corinthians 5:11]. Addiction & Grace: What about believers who have an addiction and how does grace come into this? [Galatians 5:16, Romans 6:15, Titus 2:11, Matthew 1:21].
