There are many elements that go into the total concept of fellowship, as it is described in the New Testament, but the sharing together in suffering is one of the most profitable. It probably unites our hearts together in Christ more than any other aspect of fellowship.
If you are afraid of hospitality - that you don't have much personal strength or personal wealth - good. Then you won't intimidate anybody. You will depend all the more on God's grace. You will look all the more to the work of Christ and not your own work. And what a blessing people will get in your simple home or little apartment.
