“…in order that I may gain Christ and be found in him. not having a righteousness of my own, legal righteousness but that (which is) through faith in Christ. the righteousness (which is) from God (and rests) on faith” – Philippians 3:9*
There is a purpose for us to also toss all our self-effort to please God on the refuse heap. This is a warning from the Apostle Paul for any who would think and expect that their own good deeds were in any way a righteousness that counts before God. Such “good works” will never be regarded as true righteousness. We’re to never expect God to accept us into His Kingdom based on how good we have been in life. Those that do will be disappointed. Some receiving this letter by Paul may have been offended by this. Paul says accomplishments which conformed to the Old Testament Law of Moses and the myriad of additional interpretations and traditions built up by the Jewish religious authorities since Moses. Yet it applies to any self-effort to please God and any effort by us to be righteous by following any set of laws. The only righteousness which is through faith in Christ has any value. By faith our hand extended to receive God’s free gift. Only righteousness that is imputed to the us sinners as God’s free gift is how we obtain this righteousness. Not earned, for a gift is never earned.
