We are so grateful that you have reached out for prayer and support for your son and your grandchildren. Drug addiction is a powerful stronghold, but we serve a God who can break every chain and set your son free. We stand with you in the name of Jesus Christ, the only name by which we can be saved. As it is written 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.
Firstly, we pray for your son's deliverance from drug addiction. We declare that the same power that raised Jesus from the dead is working in your son's life to set him free from this bondage. As it is written in Romans 8:11 WEB:
But if the Spirit of him who raised up Jesus from the dead dwells in you, he who raised up Christ Jesus from the dead will also give life to your mortal bodies through his Spirit who dwells in you.
We also pray for your son's complete healing, physically, emotionally, and spiritually. We declare that the peace of God, which surpasses all understanding, will guard his heart and his mind in Christ Jesus. As it is written in Philippians 4:7 WEB:
And the peace of God, which surpasses all understanding, will guard your hearts and your thoughts in Christ Jesus.
Regarding the restoration and reunification of your son with his children, we pray that God will work in the hearts of all involved, turning them towards each other with love and forgiveness. We declare that the same God who can reconcile us to Himself is able to reconcile your son with his children. As it is written in Colossians 1:20 WEB:
And through him to reconcile all things to himself, by him, whether things on the earth, or things in the heavens, having made peace through the blood of his cross.
We also pray for protection over your son and his children. We declare that no weapon formed against them will prosper, and every tongue that rises against them in judgment they will condemn. As it is written in Isaiah 54:17 WEB:
No weapon that is formed against you will prevail; and you will condemn every tongue that rises against you in judgment. This is the heritage of the servants of Yahweh, and their righteousness is of me, says Yahweh.
Finally, we encourage you to continue praying and believing. God hears your prayers, and He is faithful. As it is written in 1 John 5:14-15 WEB:
This is the boldness which we have toward him, that, if we ask anything according to his will, he listens to us. And if we know that he listens to us, whatever we ask, we know that we have the petitions which we have asked of him.
You are not alone in this struggle. We are standing with you in prayer, believing God for a miracle in your son's life and in the lives of your grandchildren. Keep trusting in the Lord, and may His peace and comfort be with you all.
Let us pray:
Heavenly Father, in the name of Jesus Christ, Your Son and our Lord and Savior, we come before You, lifting up our brother who is struggling with drug addiction. Lord, we ask for Your divine intervention in his life. Set him free from this bondage, and heal him completely - body, soul, and spirit. Comfort him in his depression, and restore to him the joy of his salvation. We also ask for restoration and reunification between him and his children. Turn their hearts towards each other, and let Your love and forgiveness flow between them. Protect them, Lord, from all harm and danger. In the name of Jesus Christ, we pray. Amen.
