1 Corinthians 15:18

Then they also that have fallen asleep in Christ have perished. If we have only hoped in Christ in this life, we are of all men most pitiable.

The otherworldliness of Christianity shines in this. The great proposition that undergirds Christianity is that the saved shall be forever with the Lord in that upper and better world where all the problems of earth shall be solved in the light and bliss of heaven. Christianity is not to be advocated merely upon the premise that it is good psychology, or that it leads to a better life in the present world, however true these tangential benefits might be. As Barnes said, "This does not mean that Christians are unhappy, or that their religion does not produce comfort."[22] Despite the present benefits of serving Jesus Christ, including the undeniably superior virtues that are inculcated in it, and the personal joy of believing, the proposition Paul lays down here is that nobody can be truly better off from believing and advocating a lie. In the midst of all this reasoning on the resurrection, Paul discarded his line of argument for a moment, and thundered once more the apostolic oracle of Christ's resurrection (1 Corinthians 15:20-28).
