The passage discusses Paul's view that everything else is worthless compared to knowing Christ. Paul considered his own righteousness through obeying the law as garbage, so that he could gain Christ and be made righteous through faith. He wants to know Christ's power in suffering and death so that he can experience resurrection. Righteousness depends on faith in Christ, not works of the law. Paul surrendered his will and effort by humbly accepting Christ's righteousness. A righteousness of surrender and dependence on what Jesus has done through trusting in him.
