Triumphal Entry on Whose Terms? (Luke 19:28-40)

Many Bibles title Luke 19:28-40 as the Triumphal Entry. I have no problem with this title, but why do we call it the triumphal entry? Christ is going to the cross, He is going to die, and ultimately the leaders of Israel deny His authority. If this is true how is it triumphal? If Christ is the one who brings peace how can this be with division? Is this sending Christ to the cross something that is surprising to Christ or was this already predicated by the prophets? If you are curious about these questions please stay tuned to our sermon titled, "Triumphal Entry on Whose Terms?"
