Why is inviting someone into your home for a meal important for truly knowing them?
A shared meal in the home moves a relationship beyond casual contact, where people may see each other once or twice a week yet never truly know one another. In that home setting, family life, children, and grandchildren are opened up, and everything is laid out for deeper fellowship and personal knowledge.
Les teaches that when believers were separated from the mainstream of Judaism, the only place they could really talk together was in their own little groups of fellowship, where they had meals together. He observes that people can know someone ever so long in casual relationships, perhaps seeing them once or twice a week, but they do not really get to know them, their children, or their grandchildren until they invite them into their home for a meal. When that invitation happens, everything is just laid out; it is not about begging for a meal, but about the openness that comes with home fellowship. This connects with the fellowship, breaking of bread, and prayer mentioned in the context.
