1 Corinthians 15:14-20

14And if Christ has not been raised, our preaching is useless and so is your faith. 15More 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. 16For if the dead are not raised, then Christ has not been raised either. 17And if Christ has not been raised, your faith is futile; you are still in your sins. 18Then those also who have fallen asleep in Christ are lost. 19If only for this life we have hope in Christ, we are of all people most to be pitied. 20But Christ has indeed been raised from the dead, the firstfruits of those who have fallen asleep.
