“and be found in him, not because I have my own righteousness derived from the law, but because I have the righteousness that comes by way of Christ’s faithfulness – a righteousness from God that is in fact based on Christ’s faithfulness…..Not that I have already attained this – that is, I have not already been perfected – but I strive to lay hold of that for which Christ Jesus also laid hold of me. Brothers and sisters, I do not consider myself to have attained this. Instead I am single-minded: Forgetting the things that are behind and reaching out for the things that are ahead, with this goal in mind, I strive toward the prize of the upward call of God in Christ Jesus. Therefore let those of us who are “perfect” embrace this point of view. If you think otherwise, God will reveal to you the error of your ways.” Philippians 3:9, 12-15 NET https://bible.com/bible/107/php.3.9-15.NET
Easter is the celebration of the resurrection of Jesus Christ, the God-Man. His death on Good Friday was the substitutionary punishment for all those who acknowledge their disobedience before God. His resurrection is proof of God the Father accepting the sacrifice of God the Son. It is the means for appropriating to all who repent before God in this life righteousness, holiness, and perfection for living in the next life with God. Jesus is the Savior because Jesus lived a perfect life on earth. He never disobeyed God but obeyed every command perfectly all of His days. His faithfulness made possible forgiveness to all who come before God repentant of their disobedience to God. What should we do if nothing is necessary to earn God’s favor for entering His heaven? If God appropriates righteousness to the repentant, what should the repentant do? They should continue to live as Jesus did, living as people made righteous by Jesus. The people who come to God in Jesus the Savior should live as God the Savior by obeying God and serving others to win them to repentance in Jesus the Savior of the world.
