Encompassed by the LORD

What was the purpose that God ordained this hour for Christ? What significance is the name Bethany, as the 'house of misery' where Martha, Mary and Lazarus lived? How do we see Jesus directing all the events down to the preparation of the donkey for the disciples to acquire? Why did Christ come to the earth as King? Why is it so significant that Christ rode on the donkey and not a horse and how did this fulfill the Old Testament prophecy? How is this day of Christ's death, the day made for rejoicing?
