Without the Resurrection, Death Would Have Won
In the Eastern Orthodox Church, part of the Pascha liturgy—the feast of the Resurrection, proclaims in song, "Christ is risen from the dead, trampling down death by death, and on those in the grave bestowing life." Paul expresses the same this way, "When the perishable has been clothed with the imperishable, and the mortal with the immortal, then the saying that is written will come true: 'Death has been swallowed up in victory.'"
Here’s a question to ponder:
"Where, O death, is your victory?
Where, O death, is your sting?"
All who believe in Christ, and His Resurrection know Paul’s answer. "The sting of death is sin, and the power of sin is the law. But thanks be to God! He gives us the victory through our Lord Jesus Christ." I Corinthians 15: 54-56. This is why we must believe.
