In Vain?

Is what we do in vain? Let 1 Cor 15:14-22 answer this question.

14And if Christ has not been raised, then our preaching is in vain and your faith is in vain. 15We 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. 16For if the dead are not raised, not even Christ has been raised. 17And if Christ has not been raised, your faith is futile and you are still in your sins. 18Then those also who have fallen asleep in Christ have perished. 19If in this life only we have hoped in Christ, we are of all people most to be pitied.
20But in fact Christ HAS been raised from the dead, the firstfruits of those who have fallen asleep. 21For as by a man came death, by a man has come also the resurrection of the dead. 22For as in Adam all die, so also in Christ shall all be made alive!!!!!
