The Triumphal Entry teaches us quite a bit about Messiah’s kingship:
First, Messiah enters riding a young donkey. Donkeys are kingly animals. David rode on a donkey and his son Solomon also rode on a donkey.
Secondly, the donkey is not a military animal. It is not powerful or war-like. Hence, Messiah comes not as a war-king–though He will come as one in AD 70–but He comes as one bringing peace on earth and good-will toward men. The Romans, and other leaders sought peace, but to no avail, Christ’s coming brings peace without the sword.
Finally, the donkey is the Messianic animal because it is humble and dependable. The Messiah does not come in pomp and glory, but in humility and faithfulness to His Father’s will.
