(Philippians 3:9-11) 9 and be found in him (Christ), not having a righteousness of my own that comes from the law, but that which comes through faith in Christ, the righteousness from God that depends on faith— 10 that I may know him and the power of his resurrection, and may share his sufferings, becoming like him in his death, 11 that by any means possible I may attain the resurrection from the dead
Believing that following rules (laws) makes you any closer to God is false. If it were true then the death of Jesus would not have been necessary. God wouldn’t have had prophets telling of our eternal king alongside the laws of the Old Testament if they were sufficient. The scripture above tells us that the righteousness of God is found in Jesus. Trusting in the law for “righteousness of our own” is a neglecting of Christ and a belief that our righteousness is better than God’s. It means not having ‘faith’ in the ‘power of His resurrection’.
In God’s desire to reconcile YOU to Him for all eternity, He decided to fulfill the law with the blood of the Savior one last time. The law required blood without blemish to forgive sin. God became the only sinless man who will ever exist for the purpose of showing the power of the spirit, the example of Godlikeness, then suffering and dying for YOU. If God has chosen to fulfill the law, then why do some people choose to turn back and ignore the new covenant for the old? Accepting Christ means allowing the Spirit to indwell in you and show forth fruit, against such things there is no law (Galatians 5:23).
