As a fully functioning member of the family of God, we hold some responsibility to the world around us. We are the salt and light needed for the kingdom to be released. That doesn’t mean that we have to take on the Taliban like Malala Yousafzai, the young girl who was shot for supporting the education of girls in Pakistan. But we are all responsible for doing something.
What we do to do good is an individual matter. It may be that when you see someone with an obvious physical disability, you ask to pray for them. (It will bless them more than you know.) It may mean that you get involved with local government to pray over the laws being passed in your city. It may mean you prayer walk your neighborhood and get to know your neighbors and bless them.
There are any number of ways to affect change all by yourself, or in connection with others. Just don’t assume that you don’t have to do anything. Jesus told the story of those cast out of the kingdom for not visiting the sick, those in prison, or feeding the hungry. We are community, and that means caring about other people and doing something about it. Now, what are you going to do?
