Matthew Poole and continuators on 1 Corinthians 15:17

17 And if Christ be not raised, your faith is vain, ye are yet in your sins .

That is, ye are yet in your estate of Nature, under the guilt and condemning power of your sins, which are not yet pardoned to you; for no sins are remitted, but upon believing in the Lord Jesus Christ, which none can do, if Christ be not risen from the dead; for by that he was declared to be the Son of God with power: his Death declared him to be truly Man, it was his Resurrection that manifested him to be truly God, God over all blessed for ever; and so the proper object of peoples Faith.
