The encounter Abraham and Sarah have with their heavenly guests in Genesis 18 is narrated in a fascinating way and conveys an important message. The text teaches us about the power of God and therefore should give us hope. In addition, the passage reminds us of the need to provide hospitality and care to others, those we know as well as strangers. As we read in Hebrews 13:2, "Do not neglect to show hospitality to strangers, for thereby some have entertained angels unawares."
