John Gill Commentary 1 Corinthians 15:13

"But if there is no resurrection of the dead, neither hath Christ been raised:" — 1 Corinthians 15:13 (ASV)

But if there be no resurrection of the dead
If there is no such thing as a resurrection of any, if the thing is not possible, if it never has been, is, or will be true in fact:

then is Christ not risen .

The apostle argues from a general, to a particular; from the general resurrection of the dead, to the particular resurrection of Christ; and from a negation of the one, to a negation of the other.

For what does not agree with the whole, does not agree with the part; and what is true of the whole, is true of the part.

But if the resurrection of Christ is not true, many are the absurdities that must follow upon it, and which the apostle next enumerates.
