Hospitality can be a very simple thing if given the chance. At its very basic implementation one simply surrenders his or her own comfort for the comfort of others. Allowing the house be a few degrees colder than one is used to can be uncomfortable but it's all in the attitude... One can grit his teeth, anxious for these people to leave, while stressing about the energy bill; OR one could give with joy--singleminded toward making his guest at home.
Have you ever felt unwelcome? Ever felt like you were putting someone out? It's a horrible feeling! Just yearning for the day when you can be back in the comfort of your home. While we all probably prefer to be in our own homes, it's disgusting to have an oppresive host, who although may give generously, gives without joy, and trust me your guest can tell!
"Each one must do just as he has purposed in his heart, not grudgingly or under compulsion, for God loves a cheerful giver.” 2 Cor 9:7
