We understand that you're witnessing strange behavior after your first cousins visited, and you're seeking the Lord Jesus' intervention. We're here to pray with you and provide biblical guidance.
Firstly, we commend you for turning to Jesus in this situation. It's important to remember that it is only by the name of Jesus that we have access to God, as it is written in John 14:6 WEB: "Jesus said to him, I am the way, the truth, and the life. No one comes to the Father, except through me." And as it says in Acts 4:12 WEB "There is salvation in none other, for neither is there any other name under heaven, that is given among men, by which we must be saved."
In times of distress or uncertainty, God calls us to pray. As it says in Philippians 4:6-7 WEB: "In nothing be anxious, but in everything, by prayer and petition with thanksgiving, let your requests be made known to God. And the peace of God, which surpasses all understanding, will guard your hearts and your thoughts in Christ Jesus."
However, we must also be sober-minded and vigilant, as strange behavior could indicate spiritual influences that are not from God. As it says in 1 Peter 5:8 WEB: "Be sober and self-controlled. Be watchful. Your adversary, the devil, walks around like a roaring lion, seeking whom he may devour."
We need to pray for your cousins and the situation, but we must also consider if there are any ungodly influences or practices that may have opened the door to these strange behaviors. As followers of Christ, we are called to be discerning and to avoid all forms of evil. As it says in 1 Thessalonians 5:22 WEB: "Abstain from every form of evil."
Let us pray together:
Heavenly Father, we come before you in the mighty name of Jesus Christ. We plead the blood of Jesus over this situation and over the lives of our dear cousin and their family. Lord, if there are any ungodly influences or practices that have opened the door to these strange behaviors, we rebuke them now in Jesus' name. We bind the enemy and command him to flee, for it is written that he must submit to us in the name of Jesus.
Lord, we pray for your healing and restoration in this situation. We pray that you would bring peace and order, and that you would draw our cousins closer to you. Surround them with your love and protection, and give them a heart that longs to serve you.
Father, we also pray for our dear requester. Give them your wisdom and discernment in this situation. Help them to be a light in the darkness, and to walk in your truth and your light.
In Jesus' name, we pray. Amen.
