Charles Spurgeon Commentary Philippians 3:9

"and be found in him, not having a righteousness of mine own, [even] that which is of the law, but that which is through faith in Christ, the righteousness which is from God by faith:" — Philippians 3:9 (ASV)

And be found in him, not having mine own righteousness, which is of the law, but that which is through the faith of Christ, the righteousness which is of God by faith:

It must be more glorious to be justified by God than by ourselves. It must be more safe to wear the righteousness of Christ than to wear our own. Nothing can so dignify our humanity as to have Christ himself to be the Lord our Righteousness. This Paul chose in preference to everything else.

Not having my own righteousness, which is of the law,

He does not say, not trusting it, but not even having it, not counting it, not thinking it worthwhile to put down among his possessions that which he once prized so much.
