Robert E. Webber said this quote

To summarize, Easter Sunday is the most important Sunday. It is the Sunday of all Sundays. It is the day of the new beginning of the entire cosmos, the day of resurrection. In our worship we must be careful not to reduce our message to the Easter fact only. The Easter fact must include the message this fact proclaims: God makes all things new. It must also include the message that we have been raised with Christ. Calling God's people to die to sin and rise to the new life is central not only to Easter day but to the Easter season.
