Morning Bible Study: What the Bible Says About Righteousness, Philippians 3:8-9

Philippians 3:8 More than that, I also consider everything to be a loss in view of the surpassing value of knowing Christ Jesus my Lord. Because of him I have suffered the loss of all things and consider them as dung, so that I may gain Christ 

9 and be found in him, not having a righteousness of my own from the law, but one that is through faith in Christ—the righteousness from God based on faith.

Commentary
(the following is from Matthew Henry's Concise Commentary, 1706 -- www.christianity.com)

"The apostle had his heart upon Christ as his righteousness. This is illustrated in several instances. 

• 1. He desired to win Christ; and an unspeakable gainer he would reckon himself if he had but an interest in Christ and his righteousness, and if Christ became his Lord and his Savior: That I may win him; as the runner wins the prize, as the sailor makes the port he is bound for. The expression intimates that we have need to strive for him and after him, and that all is little enough to win him. 
• 2. That he might be found in him (v. 9), as the manslayer was found in the city of refuge, where he was safe from the avenger of blood, Num. 35:25. Or it alludes to a judicial appearance; so we are to be found of our Judge in peace, 2 Pt. 3:14. We are undone without a righteousness wherein to appear before God, for we are guilty. There is a righteousness provided for us in Jesus Christ, and it is a complete and perfect righteousness. None can have interest or benefit by it but those who come off from confidence in themselves, and are brought heartily to believe in him. "Not having my own righteousness, which is of the law; not thinking that my outward observances and good deeds are able to atone for my bad ones, or that by setting the one over against the other I can come to balance accounts with God. No, the righteousness which I depend upon is that which is through the faith of Christ, not a legal, but evangelical righteousness: The righteousness which is of God by faith, ordained and appointed of God." 

The Lord Jesus Christ is the Lord our righteousness, Isa. 45:24; Jer. 23:6. Had he not been God, he could not have been our righteousness; the transcendent excellence of the divine nature put such a value upon, and such a virtue into, his sufferings, that they became sufficient to satisfy for the sins of the world, and to bring in a righteousness which will be effectual to all that believe. Faith is the ordained means of actual interest and saving benefit in all the purchase of his blood. It is by faith in his blood,Rom. 3:25."
