Hurricane Harvey has been very destructive for the people along the Texas coast, especially in the Houston area. Instead of doing a door offering, here are a couple of places where you can contribute money or find other ways to help those in need.
First, the Texas District website has a section with updates and a place to give. That web address is: https://txlcms.org/how-can-i-help-hurricane-harvey/# (or just go to: https://txlcms.org).
You can also donate to Lutheran ChurchCharities. Their website is: http://www.lutheranchurchcharities.org/
