Exodus 12:42; 13:10 It is a night to be much observed unto the Lord for bringing them out from the land of Egypt: this is that night of the Lord to be observed of all the children of Israel in their generations….Thou shalt therefore keep this ordinance in his season from year to year.
The people of God are told to observe this night of Passover every year in faith and thanks to the Lord for bringing them out from Egypt (the world). This special night is instituted to be observed by believers in every generation since that first night. This is the response of the observant Jews ever since.
On one fateful Passover celebration the Lamb of God (Jesus Christ, God’s Son, our Savior) celebrated the Last Feast with His disciples and was crucified as the Lamb who was sacrificed to redeem all people from Sin. The Passover and Exodus deliverance of Israel turned into the Christ Event, which saved all people from Sin, Death and the Devil.
Since that fateful Good Friday the faithful Jesus people, the people of God, the New Israel, the Church, has responding to their Salvation, which belongs to God, with an observance of that night. Christians celebrate yearly the pass over of judgment upon their sin during Holy Week and Easter, the Highest Feast of the year. Christians also observe weekly the Lord’s Supper in God’s Service to us every Sunday. Finally devout Christians remember their Baptism in daily repentance and renewed faith every morning in a daily quiet time with God in the Bible and prayer.
In this way the faithful believer responds to the grace of God by observing that night for the refreshing of faith in the forgiveness of sins, the gift of eternal life, and the great Salvation of God.
