The whole life of Christian community should be conceived as a festival in which with love,joy and boldness we celebrate what God has done for us through Christ. Especially in the festival of Jewish feast: The Passover..~Christ, our Passover lamb,has been sacrificed,Therefore let us keep the festival....'(1Cor.5:7) In this celebration we find ourselves,caught up in the worship of heaven ,so that we join`with angels and achangels,and with all the company of heaven'in giving God glory. And because the worship of God is in essence the acknowledgement of his worth, we unite with the heavenly chorus in singing of his worthiness as both Creator and Redeemer: `You are worthy,our Lord and God, to receive glory and honor and power, for you created all things, and by your will they were created and have their being'(Rev.4:11) `Worthy is the Lamb,who was slain, to receive power and wealth and wisdom and strenth and honor and glory and praise!'(Rev.5:12)
