12 Now 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?
13 But if there is no resurrection of the dead, then Christ is not risen.
14 And if Christ is not risen, then our preaching is empty and your faith is also empty.
20 But now Christ is risen from the dead, and has become the firstfruits of those who have fallen asleep.
