William Burkitt on Philippians 3:11

By the resurrection of the dead, here, is not to be understood the general resurrection, for all men shall attain to that, whether they strive for it or no; but he intends that complete holiness, and absolute perfection in grace, which shall attend the state of the resurrection; so he explains it himself in the next verse, Not that I have already attained, &c. or am already perfect; and he shows how diligent he was in endeavouring, in the use of all possible means, to arrive at it, and attain unto it.

Learn, That the glorious resurrection of the just, or grace consummated in glory, is attainable, and deserves and requires the utmost care and diligence of the most holy and zealous Christians to be exerted and put forth, in order to the attaining of it: If by any means I may attain to the resurrection of the dead.
