In comparing the accounts of Matthew 17 and Revelation 1, it is evident that the risen Christ had not yet achieved full glorification prior to his ascension. This is suggested by the fact that those who encountered him, such as Mary Magdalene and the disciples on the Emmaus road, did not immediately recognize him. This indicates that his divine identity was not fully revealed at that time.
This notion challenges the understanding of Christ's glorification, as one would expect that a fully glorified being would not be hidden or unrecognized by his followers. For instance, when Peter and the other apostles saw him on the shore, they also did not discern who he was right away. Such instances imply a transition period in Christ's nature post-resurrection, which Randy Alcorn explores in his book "Heaven."
