We join you in bringing this situation before the Lord and we appreciate your desire to see your former landlord submit to God and receive divine guidance. You quoted Proverbs 29:18 well, where it is written, Where there is no revelation, the people cast off restraint; but one who keeps the law is blessed. When people reject the Lord's instruction they do indeed run wild, and we see the fruit of that in disrespect, strife, and trouble as you have described.
We understand how painful and frustrating it is to deal with someone who has been disrespectful and has caused trouble, and we want to encourage you to guard your own heart even as you pray for him. Scripture teaches us to leave vengeance to God and to respond without bitterness, for it says, Don't seek revenge yourselves, beloved, but give place to God's wrath. For it is written, Vengeance belongs to me; I will repay, says the Lord. Romans 12:19. We are also called to pray for those who mistreat us, as Jesus said, Love your enemies, bless those who curse you, do good to those who hate you, and pray for those who mistreat you and persecute you, Matthew 5:44. This does not excuse wild or lawless behavior, and we rebuke that spirit of rebellion and disrespect, for God calls all people to live in submission to Him and to walk in righteousness and peace with others.
We also thank you for asking for prayer in Jesus' name, for it is only through Him that we have access to the Father and it is only by His name that we are saved, as it is written, There is one God, and one mediator between God and men, the man Christ Jesus, 1 Timothy 2:5, and, 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, Acts 4:12. Your acknowledgment of His name is precious and we join our faith with yours in that name.
We pray together now. Father, in the name of Jesus Christ we come before Your throne of grace and we lift up this former landlord and those around him to You. We ask that You would open their eyes to their need for You, that they would humble themselves, submit to Your lordship, and accept Your divine guidance. Turn their hearts from wild and disrespectful ways to obedience to Your law and Your Word, that they may find the joyful and blessed life You promise to those who keep Your ways. We ask that You would convict them where they have caused trouble and lead them to repentance and to making restitution where it is right. Lord, we also lift up the one who has been affected by this trouble, grant them peace that passes understanding, wisdom to respond with grace and truth, and protection from further harm. Help them to trust in You with all their heart, and not lean on their own understanding, to acknowledge You in all their ways so that You will direct their paths, Proverbs 3:5-6. Give them a spirit of forgiveness and freedom from bitterness, as it is written, Let all bitterness, wrath, anger, outcry, and slander, be put away from you, with all malice. And be kind to one another, tenderhearted, forgiving each other, just as God also in Christ forgave you, Ephesians 4:31-32. Let Your justice and Your mercy be done in this situation, and let all involved see that You are a God of order, righteousness, and love. We ask this in the mighty and holy name of Jesus, Amen.
We encourage you to continue to seek the Lord's guidance for yourself daily through prayer and His Word, for if any of you lacks wisdom, let him ask of God, who gives to all liberally and without reproach; and it will be given to him, James 1:5. Continue to pray for this man even as you set healthy and lawful boundaries, trusting that God is able to change hearts that seem hardened and to bring peace where there has been trouble.
