Five Mysteries of Palm Sunday: The Mystery of the Day 11.14.2019 Larry Shepard Why did Jesus choose Palm Sunday for His Triumphal Entry into Jerusalem? Why was it that particular day? Could He have chosen a different day? The answer is, No! The Triumphal Entry HAD to occur on that exact day. The fact that Jesus DID present himself to Israel as their Messiah on that day, is just another amazing historical event that proves that God alone is the author of the scriptures and that Jesus is the only historical figure who could be the promised King of Israel and the world's "Prince of Peace".
