Anonymous, we are truly saddened to hear about the trials your family is facing, and we stand with you in prayer and in the power of Jesus' name. The forces of darkness are real, but we know that Jesus has overcome the world (John 16:33 WEB) and has given us authority to trample on serpents and scorpions, and over all the power of the enemy (Luke 10:19 WEB).
Firstly, let's address the root of the issues you're facing. The Bible is clear about sexual immorality and adultery, which is what your children's father engaged in. It's a sin that can open doors to spiritual oppression. Jesus Himself said, "You shall not commit adultery" (Matthew 5:27 WEB). It's important to acknowledge this and pray for his deliverance and repentance.
The objects you found, such as the ball of hair and the woman's nightgown, are indicative of witchcraft practices. Engaging in such practices or having them done against you is strictly forbidden and condemned in the Bible. As it is written, "There shall not be found with you anyone who uses divination, a soothsayer, or an enchanter, or a sorcerer, or a charmer, or someone who consults a spirit of the dead, or a wizard, or a necromancer. For whoever does these things is an abomination to Yahweh" (Deuteronomy 18:10-12 WEB).
Let's pray together:
"Father, in the name of Jesus Christ, we come before You, pleading the blood of Jesus over Anonymous and her family. We rebuke every evil spirit that has been assigned against this family and command it to flee in Jesus' name. We bind the power of witchcraft and loose the power of the Holy Spirit upon this family. Lord, we ask for the deliverance and repentance of the children's father. Restore this family, Lord, and let Your love and healing power flow over them. In the name of Jesus Christ, we pray. Amen."
We encourage you to continue praying, Anonymous. Put on the whole armor of God, that you may be able to stand against the wiles of the devil (Ephesians 6:11 WEB). Remember, "God is our refuge and strength, a very present help in trouble" (Psalm 46:1 WEB).
Lastly, we noticed that your request does not mention the name of Jesus. It is only by His name that we have access to God. As it is written, "For 'Whoever will call on the name of the Lord will be saved.'" (Romans 10:13 WEB). We encourage you to place your trust in Jesus and call upon His name in your times of need.
