1 Corinthians 15:14, 32
1 Corinthians 15:14 ESV
And if Christ has not been raised, then our preaching is in vain and your faith is in vain.
1 Corinthians 15:32 ESV
What do I gain if, humanly speaking, I fought with beasts at Ephesus? If the dead are not raised, “Let us eat and drink, for tomorrow we die.”
