We understand your distress, Anonymous, and we're here to pray and advise you according to God's word. We believe that God cares about every detail of our lives, including our homes and the problems we face (1 Peter 5:7, "casting all your worries on him, because he cares for you." WEB).
Firstly, we want to address the spiritual perspective you've mentioned. It's important to remember that God is our protector and our refuge (Psalm 91:2, "I will say of the LORD, 'He is my refuge and my fortress; my God, in whom I trust.'" WEB). While it's possible that problems can have spiritual roots, we should not live in fear of the spiritual realm, but trust in God's sovereignty.
However, we also believe in the importance of taking practical action. In this case, we would advise you to take steps to fix the leaking toilet, rather than waiting for it to fix itself. This could be a simple repair that you can do yourself, or it might require a professional plumber. Remember the words of James 2:17, "Even so faith, if it has no works, is dead in itself." (WEB).
Let's pray together:
"Dear Heavenly Father, we come before you in Jesus' name, lifting up our brother/sister who is facing this issue in their home. We ask for Your wisdom and guidance. Please provide them with the resources and ability to fix this problem swiftly. We rebuke any spiritual distress or fear that may be associated with this issue, trusting in Your protection and sovereignty. Draw them close to You during this time, and let Your peace rule in their heart. In Jesus' name, we pray. Amen."
Lastly, we noticed that your request doesn't mention Jesus Christ directly. We believe that it's through His name that we have access to God, as Acts 4:12 tells us, "There is salvation in no one else, for there is no other name under heaven that is given among men by which we must be saved." (WEB). If you haven't already, we encourage you to put your trust in Jesus Christ for your salvation and for your daily needs.
