1 Corinthians 15:14-23

and if Christ has not been raised, then our preaching is vain [useless, amounting to nothing], and your faith is also vain [imaginary, unfounded, devoid of value and benefit—not based on truth]. We are even discovered to be false witnesses [misrepresenting] God, because we testified concerning Him that He raised Christ, whom He did not raise, 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 worthless and powerless [mere delusion]; you are still in your sins [and under the control and penalty of sin]. Then those also who have fallen asleep in Christ are lost. If we who are [abiding] in Christ have hoped only in this life [and this is all there is], then we are of all people most miserable and to be pitied. But now [as things really are] Christ has in fact been raised from the dead, [and He became] the first fruits [that is, the first to be resurrected with an incorruptible, immortal body, foreshadowing the resurrection] of those who have fallen asleep [in death]. [Col 1:18] For since [it was] by a man that death came [into the world], it is also by a Man that the resurrection of the dead has come. For just as in Adam all die, so also in Christ all will be made alive. But each in his own order: Christ the first fruits, then those who are Christ’s [own will be resurrected with incorruptible, immortal bodies] at His coming.
