Let brotherly love continue. Don’t neglect to show hospitality, for by doing this some have welcomed angels as guests without knowing it.
(Hebrews 13:1-2 HCSB ©®)
Hospital and hospitality are closely related words. (At least, the concept of a hospital is related to hospitality. The current business model of hospital fits neatly into the industry governed poorly by the FDA and the CDC and mammon.)
There are times when we make sacrifices to bless someone that turn out to be much greater blessings for us than for the person we intended to help. Some of the encounters will be with spirits sent from the throne of Yahweh with messages or other blessings, and sometimes when we were feeding or otherwise blessing someone, we were actually blessing Jesus Himself (Matthew 25:40).
The sacrifices can be small or great. The key to the blessing is being obedient when the Spirit says to answer someone with hospitality.
