...I love offering an ear to listen and some prayer time to a distressed brother and rejoicing with them when it's warrented. Simply buying someone lunch can make a huge difference when they are really struggling with depression, loneliness, or isolation.
As far as helping others goes, in full disclosure, I really struggle with the ministry of hospitality. I feel like I can go out to help others all the day long, but it's really a discipline for me to open my home to someone. I don't know if the root of this is American "castle" ideology or an introverted personality or both or something else.
