14. your faith . . . vain— (1Co 15:11). The Greek for "vain" here is, empty, unreal: in 1Co 15:17, on the other hand, it is, without use, frustrated. The principal argument of the first preachers in support of Christianity was that God had raised Christ from the dead (Ac 1:22; 2:32; 4:10, 33; 13:37; Ro 1:4). If this fact were false, the faith built on it must be false too.

     17. vain—Ye are, by the very fact (supposing the case to be as the skeptics maintained), frustrated of all which "your faith" appropriates: Ye are still under the everlasting condemnation of your sins (even in the disembodied state which is here referred to), from which Christ's resurrection is our justification (Ro 4:25): "saved by his life" (Ro 5:10).
