It is impossible to overemphasize the importance of the Resurrection!

"The resurrection isn't just a surprise happy ending for one person; it is instead the turning point for everything else."  - N. T. Wright, Surprised by Hope: Rethinking Heaven, the Resurrection, and the Mission of the Church. New York: HarperCollins, 2008, p236.

1 Corinthians 15:17 If Christ has not been raised, your faith is vain; you are still in your sins. 18 Then they also who are fallen asleep in Christ have perished. 19 If we have only hoped in Christ in this life, we are of all men most pitiable.
20 But now Christ has been raised from the dead. He became the first fruits of those who are asleep. 21 For since death came by man, the resurrection of the dead also came by man. 22 For as in Adam all die, so also in Christ all will be made alive. (World English Bible, public domain)
