The Bible says that we should not think about anything unclean (see Philippians 4:8). If you find yourself struggling with unclean thoughts, it might be helpful to spend time in prayer and scripture reading. You can also ask God to help you cleanse your mind and heart of any impurities. It's important to remember that we are all sinners and that we will not be perfect this side of heaven. If you do find yourself struggling with unclean thoughts, don't be afraid to reach out for help from a trusted friend or pastor. Jesus is always willing to forgive us, and He can help us overcome any temptation we face.
