We understand that you are facing a challenging situation with your nephew and son living with you, and we are here to pray and provide counsel based on the Word of God.
Firstly, we commend you for bringing this matter to the Lord in Jesus' name. It is only in His name that we have access to God the Father and can find true help and victory and you correctly finished your request by saying I Jesus Name and Amen correctly. 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.
We must be clear before God and man on the dilemma and tell you clearly that you are right to be concerned about their behavior and the influence it may have on your household. Drug abuse and related troubles, or or any trouble generally, needs to be confronted and addressed with love and truth as a Christian. We must be clear that it is unrighteousness to abuse and be under the influence of drugs and their behavior as a pair seems inappropriate to be together if they are indulging together. So we view it as right to seek for them to be separated from your home. If there is influence encouraging trouble in your home, it should be removed.
In this situation, it is important to set boundaries and encourage them to seek godly paths. God tells us to turn away from bad company and influence: Do not be deceived: Evil companionships corrupt good morals. Wake up from your drunkenness and be sober; walk dramatically, not in reveling and drunkenness, not in chambering and wantonness, not in strife and jealousy. Instead, put on the Lord Jesus Christ, and do not take thought beforehand for the lusts of the flesh. Romans 13:13-14 WEB
Let's pray together:
Heavenly Father, we come before You in the name of Jesus, lifting up our sister who is facing a difficult situation with her nephew and son. Lord, You know the struggles and challenges she is facing, and we ask for Your divine intervention and wisdom. Help her to set godly boundaries and encourage her nephew and son to seek Your will for their lives. We pray in Jesus' name against their misguided path and to be led each individually in confidence in the Holy Spirit. We pray they would have cover over them so they can seek and find salvation from the devil they have been feeding. We pray for their conviction and correction from God. Please provide resources and to make arrangements for them while away from her home.
Father, we also pray for her peace and comfort. Help her to rest in Your promises and guidance. Grant her peaceful nights and reassurance in Your love and protection by Jesus' name. Guide her through this trial, giving her the strength and courage to do what is right and honorable before You. Provide all that she may need to achieve this.
Lastly, Father, we pray for their salvation. Call them to repentance and faith in Jesus Christ, that they may turn from their ways and follow Him, not wanting to inquire or search the world, but rather You. Please help them to be discipled and sanctified in Christ. Only then will they find true freedom and transformation. We ask all of these requests against any opposition by our adversary the devil, knowing that whoever will call on the name of the Lord will be saved. Praying in Jesus' name and the power of His blood. Amen
