I heard a challenge on this in chapel, and the passage has stuck with me

Mark 9:2-8
When we see Christ in His glory - for who He us
1. We will not doubt Him for He is the Messiah, God as man
2. We will not disregard Him, but listen to Him
These two reactions only take place when we have seen Christ in His glory! We cannot expect to trust and listen to Him without seeing Him.
