No Resurrection, No Salvation

1Cor 15:15-18 More than that, we are then found to be false witnesses about God, for we have testified about God that he raised Christ from the dead. But he did not raise him if in fact the dead are not raised. For if the dead are not raised, then Christ has not been raised either. And if Christ has not been raised, your faith is futile; you are still in your sins. Then those also who have fallen asleep in Christ are lost.

"Paul was preaching the good news about Jesus and the resurrection." Acts 17:18b

Paul believed that

"there will be a resurrection of both the righteous and the wicked." Acts 24:15

The gospel is not just about who Christ was or what he taught. It is also about the historic facts of the death, burial and resurrection, of which a large portion of the gospels of Matthew, Mark, Luke and John are devoted. It is like no other religion in this respect - founded upon historic fact - the fact of miracles, affirmed by a multitude of eyewitnesses, which the hostility of the religious elite could not suppress. One cannot be called a Christian if they deny the resurrection of Christ.

But if Christ wasn't raised, then the gospel is false. If the gospel is false, then Jesus did not atone for sin, and as such there is no provision to escape the wrath of God, and those who have died have gone to hell.
