"If Jesus is dead, then Christianity is dead. If Jesus is alive, then Christianity is alive. Paul himself declared as much in 1 Corinthians 15:17: “If Christ has not been raised, your faith is futile and you are still in your sins.”
Apart from the resurrection of Jesus Christ, there is no savior, no salvation, no forgiveness of sin, and no hope of resurrected eternal life. Apart from the resurrection, Jesus is reduced to yet another good but dead man and therefore is of no considerable help to us in this life or at its end. Plainly stated, without the resurrection of Jesus, the few billion people today who worship Jesus as God are gullible; their hope for a resurrection life after this life is the hope of silly fools who trust in a dead man to give them life. Subsequently, the doctrine of Jesus’ resurrection is, without question, profoundly significant and worthy of the most careful consideration and examination."
