Apostol § 159

Brethren, if Christ is preached that He has been raised from the dead, how do some among you say that there is no resurrection of the dead? But if there is no resurrection of the dead, then Christ is not risen. And if Christ is not risen, then our preaching is vain and your faith is also vain. Yes, and we are found false witnesses of God, because we have testified of God that He raised up Christ, whom He did not raise up; if in fact the dead do not rise. For if the dead do not rise, then Christ is not risen. And if Christ is not risen, your faith is vain; you are still in your sins! Then also those who have fallen asleep in Christ have perished. If in this life only we have hope in Christ, we are of all men the most miserable.
