Hebrews 13:2

Abraham entertained angels when he showed them hospitality (Genesis 18). Hospitality (Gr. philoxenia, lit. love to strangers) is a concrete expression of Christian love today, as it was in the first century (cf. 3 John 1:5-8). [Note: For an overview of hospitality in the early church, see J. H. Elliott, Home for the Homeless: A Sociological Exegesis of 1 Peter, pp. 145-50, 165-200; and G. Bornkamm, Early Christian Experience, pp. 123-93.] Abraham received a special blessing because he showed hospitality, and we may, too (cf. Matthew 25:35). All Christians should practice hospitality (Romans 12:13), especially Christian leaders (Titus 1:8).

Have you ever entertained an angel? Since the word "angel" means "messenger," in one sense any time we entertain someone who brings a message from God (e.g., a visiting preacher or missionary) we entertain an angel. In the sense of entertaining a spirit being who comes to us in human form with a message from God, perhaps some have that privilege even today.
