Call the Network Director, who will handle problems immediately. The Host Church is to provide a stable, warm, friendly environment for a family under a lot of stress. That is what they need every night and that is what a Christian congregation can provide so well. The FPGK staff is to provide assistance to help the family overcome homeless and the varied problems that cause the homelessness. Your job is warmth and stability with no strings attached except for the Guest family to behave decently while they are in your church.
