Angels in the Bible appeared to people in three main ways: personally (Genesis 18:1–3; Luke 1:26-38), in dreams (Genesis 28:12; Matthew 1:20–21), and in visions (Zechariah 1:8; Revelation 1:9–20). Today, while angelic encounters are rare, they will align with Scripture and will not contradict God's revealed truth. Claims of frequent angelic encounters should be approached with caution, distinguishing between true messages, deceptions, and human misunderstandings. We are called to recognize God and serve Him regardless of other spiritual visitations we may receive. Angels potentially appearing to people reminds us that there is a spiritual realm and that what we see physically is not all there is.
When we discuss whether angels appear to people today, we must be careful to note that both holy angels and fallen angels (called demons) still exist. All angel visitation claims fall into one of three categories. First, they can be made up, whether intentionally or sincerely (having a human explanation). We must remember that angelic encounters were and are rare or uncommon. Even God's apostles and prophets only saw an angel on limited occasions. Anyone who claims to see angels regularly is making claims inconsistent with Scripture. Second, an angelic visit could be a deception by an evil spirit. Third, a person may have a true angelic encounter.
True angelic encounters will involve messages or activities that do not contradict God's clear revelation in Scripture. A messenger of God will not give a message that is in conflict with the truth of God since God does not lie (Titus 1:2). It is possible God sometimes communicates with an individual through angels today. In fact, many reports have come from around the world over the years regarding times when unexplained encounters have involved an individual that could best be described as an angel.
Perhaps this is one reason Hebrews 13:2 teaches, "Do not neglect to show hospitality to strangers, for thereby some have entertained angels unawares." We cannot plan for angelic encounters or simply seek them. God controls when and if an angel will appear to minister to someone in need (Hebrews 1:14). We are called to faithfully serve the Lord regardless, knowing that God works in ways beyond that which we can ask or imagine (Ephesians 3:20).
