The Passover has been called the fulcrum of the Old Testament (as the Resurrection is the apex of the New Testament). Echoes of the event rings throughout the Psalms. Even some of the prayers recorded by the Gospel writers refer to the Passover. For it was through the Passover event that God revealed His unique relationship with Israel.
Through Israel’s exile and now return, God had demonstrated His unfailing promise to this special relationship.
So Israel’s observance of the Passover was both a celebration and a worship service of thanksgiving.
And the descendants of the captivity kept the Passover on the fourteenth day of the first month. For the priests and the Levites had purified themselves; all of them were ritually clean. And they slaughtered the Passover lambs for all the descendants of the captivity, for their brethren the priests, and for themselves. Then the children of Israel who had returned from the captivity ate together with all who had separated themselves from the filth of the nations of the land in order to seek the Lord God of Israel. And they kept the Feast of Unleavened Bread seven days with joy; for the Lord made them joyful, and turned the heart of the king of Assyria toward them, to strengthen their hands in the work of the house of God, the God of Israel.
PRAY FOR ISRAEL TO CELEBRATE THEIR UNIQUE RELATIONSHIP WITH GOD BY EMBRACING HIS MESSIAH.
