If there was not one man Adam and one woman Eve, and a literal event of the one man Adam taking the fruit in rebellion and thus bringing sin and death into world, then one may as well throw the rest of the Bible away.
Jesus is the Son of God, we have a chance for God's blessings, God's salvation through our faith in Jesus Christ and all of us are sinners who fall short of the glory of God, and the wages of sin is death but through our faith that Jesus Christ, we can be saved.
If God hath made this world so fair, Where sin and death abound, How beautiful beyond compare Will paradise be found!
Therefore, don't let sinners take courage to think they will be favoured like the thief on the cross; for we see on the other side, they may be like the hardened one, and reproach death itself.
Without His Resurrection the death of Christ would be of no avail, and His grave would be the grave of all our hopes. A gospel of a dead Savior would be a miserable failure and delusion. The Resurrection is the victory of righteousness and life over sin an death.
The conversion of Paul was no conversion at all; it was Paul who converted the religion that has raised one man above sin and death.
In short, all things that please the natural man in this world, are, to a true Christian, only so many crosses and temptations, allurements of sin and snares of death, that continually exercise his virtue.
