Therefore, fourth, whatever Paul hoped to gain was something other than the normal resurrection of all believers from the dead.

Clearly more than faith in Christ is involved. The word used here is an interesting one. It is brabeion. Run in such a way that you may obtain it. Commentators are widely in agreement that that passage refers to eternal rewards which believers can obtain for faithfulness in this life.
