John Wesley on Philippians 3:9

And be found by God ingrafted in him, not having my own righteousness, which is of the law - That merely outward righteousness prescribed by the law, and performed by my own strength. But that inward righteousness which is through faith - Which can flow from no other fountain. The righteousness which is from God - From his almighty Spirit, not by my own strength, but by faith alone. Here also the apostle is far from speaking of justification only.
