How They Compare To Humans
We know from Scripture that angels are stronger than man, but not omnipotent (2 Peter 2:11). We also know that they are greater than man in knowledge, but not omniscient. The Bible tells us "But about the day or hour no one knows, not even the angels in heaven, nor the Son, but only the Father" (Matthew 24:36). Sometimes these spirits take on the form of men, depending on the occasion and its demands. Scripture points out "Do not forget to show hospitality to strangers, for by so doing some people have shown hospitality to angels without knowing it (Hebrews 13:2).
