We understand your concern and are here to pray and provide guidance based on biblical principles.
Firstly, it's important to address the behaviors mentioned. The Bible tells us to "Abstain from every form of evil" (1 Thessalonians 5:22 WEB). The activities mentioned—engaging with a bad spirit, and public indecency—are indeed against God's will. We should also remember that our bodies are temples of the Holy Spirit (1 Corinthians 6:19-20 WEB), and we must honor God with our bodies.
Regarding the mention of a "bad spirit," we are reminded of Ephesians 6:12 WEB, "For our wrestling is not against flesh and blood, but against the principalities, against the powers, against the world’s rulers of the darkness of this age, and against the spiritual forces of wickedness in the heavenly places." We need to pray for protection and deliverance from such influences.
For the issue of masturbation, while the Bible does not directly mention it, the principles of sexual purity and holiness apply. Sexual activity is designed by God to be enjoyed within the bounds of marriage between a man and a woman (Hebrews 13:4 WEB). Anything outside of this can lead to spiritual and emotional harm.
Let's pray together:
"Father, we come before You in the name of Jesus, claiming Your power and authority. We pray for Chardarfean and their family. We rebuke any evil spirits that may be influencing their son and bind them in Jesus' name. We pray for deliverance, healing, and a renewed mind for both the son and the man involved in the mentioned behavior. Lord, we ask You to help them resist temptation and to draw them closer to You. Fill them with Your Holy Spirit, that they may live lives pleasing to You. We also ask for wisdom for Chardarfean, that they may know how to support and guide their family in these issues, always pointing them towards Jesus. It's in His precious name we pray, amen."
Lastly, we noticed that your request did not mention Jesus. Remember, it's only through His name that we have access to God's throne of grace (Hebrews 4:16 WEB). If you haven't already, consider accepting Jesus as your Lord and Savior. He is the mediator between God and us (1 Timothy 2:5 WEB).
