Flood victims lost home

Please help my parents who have just lost their home in a flood. 15" of rain fell in 3 days in Oklahoma which has caused severe flooding. My parents had to leave their home so quickly that they had no time to take any belongings. Everything is now lost in the flood; clothing, cars, food, furniture and personal items. Medicine and the clothes they were wearing is all they took on the rescue boat. My dad is a pastor and has a funeral service and church service on Sunday and has no suit or anything to wear. They are literally homeless at this point an could really use a blessing of help. Any support you can provide would be greatly appreciated. Thank you so much for any help you can provide.
