Let us pray:
Dear Heavenly Father,
We come before You in the name of Jesus Christ, lifting up our brother/sister in Christ who is facing this challenge. Lord, we ask that You will help them to walk in love and patience, even as they deal with the super. Father, we pray for the super as well, that You will soften his heart and help him to act with kindness and professionalism. We pray for someone to come forward and fix the leak under the bathroom sink.
If it is not the super we are praying that you will send a believer in Christ to fix the problem and provide a testimony to everyone involved. Lord, we rebuke any evil spirits that may be at work in this situation, and we ask that You will cover our brother/sister in Christ with Your protection and peace, in Jesus Christ name we pray. Amen.
