What do angels know, and what don’t they know?
Question 08135
Angels are spiritual beings of immense power and long experience, but they are not God. That distinction matters enormously when considering the scope of their knowledge. Scripture presents angelic intelligence as genuinely superior to human understanding in many respects, while also marking clear limits that set their knowledge apart from the omniscience that belongs to God alone.
What Angels Know
The biblical evidence suggests that angels possess knowledge far exceeding ordinary human awareness. They have been present throughout the history of creation. They witnessed the founding of the earth (Job 38:7), they have observed the unfolding of God’s redemptive plan across millennia, and they serve as God’s messengers, a role that itself requires a grasp of the message being delivered. Gabriel’s appearance to Daniel (Daniel 9:21–27) involved communicating one of the most complex prophetic timetables in all of Scripture, and there is no suggestion that Gabriel was merely parroting words he did not understand. The angel who interpreted Zechariah’s visions engaged in sustained theological explanation (Zechariah 1–6), and the angelic beings around God’s throne in Revelation display a knowledge of God’s holiness and purposes that shapes their unceasing worship.
Angels also demonstrate knowledge of individual human circumstances. The angel who appeared to Hagar knew her situation and her future (Genesis 16:7–12). The angel of the LORD addressed Gideon by name and with specific knowledge of his character and calling (Judges 6:12). In the New Testament, angels announced the birth of Jesus to shepherds with detailed knowledge of where the child could be found (Luke 2:10–12) and appeared to the women at the empty tomb with full awareness of what had happened (Matthew 28:5–6). These are not beings operating with limited intelligence. Their knowledge is extensive, informed by proximity to God and by ages of observation of human affairs.
What Angels Do Not Know
The most explicit statement of angelic limitation comes from Jesus Himself in Mark 13:32: “But concerning that day or that hour, no one knows, not even the angels in heaven, nor the Son, but only the Father.” Whatever else angels know, the timing of the Son’s return is hidden from them. This is not a trivial exclusion. It establishes the principle that God retains knowledge that He has not shared with any created being, however exalted. If even the angels closest to God’s throne do not know this, the scope of what remains hidden from them may be considerable.
1 Peter 1:12 adds another significant limitation, which the next article addresses in detail: “things into which angels long to look.” The mysteries of the gospel, specifically God’s plan to redeem fallen human beings through the incarnation, death, and resurrection of His Son, are things that angels observe with wonder but do not experience from the inside. They understand the facts, but the experiential reality of being a sinner saved by grace is outside their frame of reference entirely.
Angels are also not omniscient about the internal states of the human heart. Only God searches the heart and knows the thoughts of every person (1 Kings 8:39; Jeremiah 17:10). Demonic beings, who are fallen angels, clearly possess significant observational knowledge about human behaviour and can exploit patterns they have observed, but there is no biblical evidence that any angelic being, fallen or unfallen, can read human thoughts directly. That capacity belongs to God alone.
Knowledge Without Omniscience
The pattern Scripture draws is one of created intelligence operating at a remarkably high level but always within the boundaries of creaturehood. Angels know what God has revealed to them and what they have observed through their service in His presence and throughout human history. They do not know what God has chosen not to reveal, and they do not possess the intrinsic, unlimited, self-generating knowledge that belongs to God by nature. Their knowledge is received, not inherent. It grows through observation and revelation, not through the kind of exhaustive self-knowledge that characterises the divine mind.
This has a practical implication worth noting. When the woman of Tekoa told David that “my lord the king is like the angel of God to discern good and evil” (2 Samuel 14:17), she was using angelic knowledge as the highest standard of created intelligence she could imagine. Angelic understanding was proverbial for its depth and accuracy. The compliment was enormous, and the point was clear: angels were understood in Israelite thought as the most knowledgeable created beings in existence. Yet even that knowledge had its ceiling, fixed by the God who made them.
So, now what?
Understanding that angels are vastly knowledgeable but not omniscient protects believers from two errors. It guards against the assumption that angelic or demonic beings know everything, which can produce unhealthy fear of the enemy or naive trust in supposed angelic messages. And it guards against treating angels as negligible, as though the spiritual realm operates with no greater intelligence than the human one. Angels are formidable beings with profound understanding, but they remain creatures, and the knowledge that matters most for every human being, the knowledge of sins forgiven and a relationship with God through Christ, is something even the greatest angel cannot claim from personal experience.
