This is the tough part. God has asked us to do uncomfortable things for his glory, and you’ll have to reach out to others. You’ll have to ask people to coffee even if you don’t like coffee. You’ll have to choose to shake someone’s hand after church even if you’d rather slip out early.
Many times we expect others to invite or include us, especially if we’re new, but letting people know that you are willing to be included is the first step. It will not be easy sometimes, and sometimes people will say no, but many times, people will say yes, too.
