We consider Biblical love in the context of hospitality. We learn that our general use of the word today is not what was meant in Scripture. The command to us is to open our homes not primarily to those we know and with whom we are friendly (which is nonetheless a good thing to do) but rather that we should do so for strangers, in which there is a great blessing for us. As it says in Hebrews 13:2, by showing hospitality, some have entertained angels without knowing it.
Having understood what hospitality is in the context of Scripture and according to the customs of the day, we move on to look at how the principles taught here by Paul can be put into practice by believers in our day and age.
