Don’t skip past this. Settle in on this idea and let it sink down deep for a few minutes. It [gratitude] may be the key strategy God wants to use to set you free from your addiction to pornography. In this passage, God is urging Christians to replace sexual immorality with something else. He could have inspired the Apostle Paul to write anything here. Paul could have said, But instead let there be love, or mercy, or self-control, or joy. Instead of any of those wonderful things, God wanted Paul to tell Christians to replace immorality with thankfulness. This means that we need to consider why gratitude is so important to God in the fight against sexually immoral acts like pornography.
