Jesus is Alive Is Why We Celebrate

But on the first day of the week, at early dawn, they (the women) came to the tomb bringing spices which they had prepared.  And they found the stone rolled away from the tomb, but when they entered, they did not find the body of the Lord Jesus. 

While they were perplexed about this, behold, two men suddenly stood near them in dazzling clothing; and as the women were terrified and bowed their faces to the ground, the men said to them, “Why do you seek the living One among the dead?  He is not here, but He has risen.  Remember how He spoke to you while He was still in Galilee, saying that the Son of Man must be delivered into the hands of sinful men and be crucified, and the third day rise again.”

And they remembered His words, and returned from the tomb and reported all these things to the eleven and to all the rest.
