We understand your frustration and we're here to support you in prayer and guidance. We're glad to pray for you and the situation in the only name by which we can access God. That is the name of Jesus. This is also the name by which we are saved. It is only in this name that we have power to pray and rebuke.
Firstly, let's address the behavior of the man in your home. It's clear that his actions are causing you distress and discomfort, and this is not acceptable. We must remember that the Bible tells us to "Put them in mind to be in subjection to rulers, to authorities, to be obedient, to be ready unto every good work, to speak evil of no man, not to be contentious, to be gentle, showing all meekness toward all men. For we were also once foolish, disobedient, deceived, serving various lusts and pleasures, living in malice and envy, hateful, and hating one another" (Titus 3:1-3 WEB).
His behavior, including the hacking, spitting, and accusations, as well as his alcohol addiction and weed smoking, are not only disrespectful but also sinful. The Bible tells us, "Don't be drunken with wine, in which is dissipation, but be filled with the Spirit" (Ephesians 5:18 WEB). We must remember that our bodies are temples of the Holy Spirit, and we should treat them as such.
Let's pray for this man, that God may convict his heart and lead him to repentance. "If we confess our sins, he is faithful and righteous to forgive us the sins, and to cleanse us from all unrighteousness" (1 John 1:9 WEB).
Let's also pray for your health, especially your asthma, and for God's protection over you. "For I will restore health to you, and I will heal you of your wounds,' says Yahweh" (Jeremiah 30:17 WEB).
Now, let us pray:
Heavenly Father, we come before You in the name of Jesus Christ, lifting up our sister who is facing this difficult situation. Lord, we ask You to intervene and change the heart of this man who is causing distress. Convict him of his sins and lead him to repentance and restoration in his marriage.
Lord, we bind his provocative behavior, his alcohol addiction, and weed smoking in the name of Jesus. We rebuke it, destroy it, dismantle it, break it, cease it, and silence it. We plead the blood of Jesus over this situation and pray that You would restore peace and quiet in the home.
Father, we also pray for Your healing and protection over our sister's health, especially her asthma. We ask that You would surround her with Your favor and grace, and lead her in the path of righteousness.
Lord, we thank You for Your faithfulness and for hearing our prayers. We ask all these things in the precious name of Jesus Christ, our Lord and Savior. Amen.
Lastly, we encourage you to continue praying and seeking God's will in this situation. Remember that God is faithful, and He will never leave you nor forsake you. "Be strong and courageous. Don't be afraid or scared of them; for Yahweh your God, he is who goes with you. He will not fail you nor forsake you" (Deuteronomy 31:6 WEB).
Stand firm in your faith, and trust that God is working all things together for your good. "We know that all things work together for good for those who love God, to those who are called according to his purpose" (Romans 8:28 WEB).
Lastly, it is our responsibility to rebuke the sin in love, but also to love the sinner.
Finally, we encourage you to continue to believe in Jesus Christ, the only name by which we can be saved. If you have not yet done so, please repent of your own sins and ask God to forgive you of them in Jesus' name.
Prayer Focus: God, Thank You for loving me. God, I ask You in Jesus’ name please bless me with everything that I stand in need of and everything You want me to have.
