"Literal Christianity is unverifiable and therefore a matter of blind wishful thinking."
I'll let Paul answer you...
"Now if Christ is proclaimed as raised from the dead, how can some of you say that there is no resurrection of the dead?
But if there is no resurrection of the dead, then not even Christ has been raised. And if Christ has not been raised, then our preaching is in vain and your faith is in vain. We are even found to be misrepresenting God, because we testified about God that he raised Christ, whom he did not raise if it is true that the dead are not raised.
For if the dead are not raised, not even Christ has been raised. And if Christ has not been raised, your faith is futile and you are still in your sins. Then those also who have fallen asleep in Christ have perished. If in this life only we have hoped in Christ, we are of all people most to be pitied.
But in fact Christ has been raised from the dead..."
If the central events of the New Testament did not literally occur then Christian faith is a vanity and Christians are wasting their time. But, as Paul testifies, Christ did die on a literal cross and was literally raised from the dead.
One of my favorite passages:
For the word of the cross is folly to those who are perishing, but to us who are being saved it is the power of God. For it is written, "I will destroy the wisdom of the wise, and the cleverness of the clever I will thwart."
Where is the wise man? Where is the scribe? Where is the debater of this age? Has not God made foolish the wisdom of the world? For since, in the wisdom of God, the world did not know God through wisdom, it pleased God through the folly of what we preach to save those who believe.
For Jews demand signs and Greeks seek wisdom, but we preach Christ crucified, a stumbling block to Jews and folly to Gentiles, but to those who are called, both Jews and Greeks, Christ the power of God and the wisdom of God.
