Question: Why didn't the disciples recognize Jesus after the Resurrection?
Answer: The disciples' unbelief (He was the last person they expected to see) was no doubt a large factor. Moreover, the scripture explains that "their eyes were holden [prevented from seeing]..." (Lk 24:16). We are also told that he "appeared in another form..." (Mk 16:12). His resurrection body was a transformation from the one they had known before. It was glorious, but He was veiling that glory. His resurrection body had amazing qualities. Consider John's description of Jesus in Revelation 1—but that was only one aspect. In Revelation 5, the angel calls him "the Lion of the tribe of Juda[h]," but when John turns to see this "Lion," he sees a "Lamb as it had been slain." God's throne is eternally "the throne of God and of the Lamb" (Rv 22:1). It is all quite beyond our comprehension or explanation.
