What does Judges 6:22 mean?
Scripture gives us ample evidence to understand that Gideon's nature was neither daring nor confident (Judges 6:17, 27, 36–40). It's possible that when he first requested God provide proof of His identity, he was hoping to find the whole thing was a hoax. Here, rather than reacting to confirmation (Judges 6:18–21) with courage, Gideon seems to despair. He had clearly already seen the Man's face. Apparently, Gideon didn't fully believe the man was a manifestation of the Lord until fire consumed Gideon's meal and the Angel vanished into thin air.Instead of being excited, Gideon becomes disturbed and afraid. It was common knowledge that nobody can see the Lord's face and live (Exodus 33:18–23). Gideon clearly associates the Angel of the Lord with the Lord Himself—and he has seen His face! Gideon cries out, "Alas! O LORD God!" He is fearful for his life.
However, what Gideon has seen is referred to as a Theophany or a Christophany, meaning a visible, material manifestation of God, rather than God in His full and undisguised glory. God will reassure Gideon that he's not about to die (Judges 6:23).
