Robert.z.s, we understand the spiritual concern you have with the current situation. Firstly, it is important to align the hearts of your family members with the Word of God when we address issues of this manner. In Ephesians 6:12 WEB it says For we do not wrestle 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.
Let us discuss your blessing of the house, and it is great you took action. But remember, it is essential to dedicate both your home and your family to the Lord Jesus Christ. It is of utmost importance to explicitly use the name of Jesus in your prayers. In Acts 4:12 WEB it says 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.
Now, regarding the objects, it is important to understand that idols and objects tied to evil practices should have no place in a Christian home. If you can establish some dialogue if possible. There has to be a violent hatred of any ties to the evil practices and devotion to Christ. Recall the practices of the early Israelites as they were pleasing to God. In Exodus 20:3-5 WEB says You shall have no other gods before me. You shall not make for yourselves an idol, nor any image of anything that is in the heavens above, or that is in the earth beneath, or that is in the water under the earth: you shall not bow yourself down to them, nor serve them, for I, Yahweh your God, am a jealous God. In Exodus 23:13 WEB says Now concerning all that I have said to you, be aware. You shall not invoke the name of other gods, neither shall you let them be heard out of your mouth.
It is important for us to pray for the family and their openness in bringing this to the Lord. Personally withdraw yourself from them. Depart from the evil things and do not touch them. Consider removing clutter and anything that is connected to evil. Less is more, material belongings can be a distraction from God. Bring order to the space that you can control. If removal of idols and evil objects brings opposition from your family, If they seek help or if there is a conversion, there may be blessings in having a place for them to seek refuge when they are ready. Continue prayer, and fasting for your family as we pray together for them now.
Almighty Father, we come before you in the name of Jesus Christ to intercede for our brother and his family. Lord, we ask that you soften the hearts of his family members and open their eyes to see the truth of your Word. Help them to see the danger of keeping evil objects in their home and give them the strength and courage to remove these items and turn to you. We come against the unclean spiritual forces that are a part of the contents of the house and within the family members. We pray for the stories of conversion throughout the family. In Jesus Christ's name, we pray they come to closing the doors and windows of accesses to evil spirits and cleansing and healing to take place in the lives of those in the house. So, we thank you and praise you for your unfailing love and mercy. In Jesus Christ's name, we pray. We would also like to end with this verse, In 1 Peter 5:8 WEB it says Be sober and self-controlled. Be watchful. Your adversary, the devil, walks around like a roaring lion, seeking whom he may devour.
