12 But if it is preached that Christ has been raised from the dead, how can some of you say that there is no resurrection of the dead?13 If there is no resurrection of the dead, then not even Christ has been raised. 14 And if Christ has not been raised, our preaching is useless and so is your faith. 15 More than that, we are then found to be false witnesses about God, for we have testified about God that he raised Christ from the dead. But he did not raise him if in fact the dead are not raised. 16 For if the dead are not raised, then Christ has not been raised either. 17 And if Christ has not been raised, your faith is futile; you are still in your sins. 18 Then those also who have fallen asleep in Christ are lost. 19 If only for this life we have hope in Christ, we are of all people most to be pitied
I'm not sure whether it's just a coincidence but the HQ says something almost identical at HQ 6:27-28 about those who find themselves face to face with their fate in the hereafter, they “will say, "Oh, would that we were returned back [to life]: then we would not deny our Sustainer Lord's [warning] signs regarding [what we can now see as real] and we would be among the believers!" But nay -[they will say this only because] the truth which they used to conceal [from themselves] in the past will have become revealed to them [as truth which they now wanted to escape]; and if they were returned back, they would certainly return to the very thing which was forbidden to them: for behold, they are just [compulsive] liars”
