Whatever happens, my dear brothers and sisters, rejoice in the Lord. I never get tired of telling you these things, and I do it to safeguard your faith. Watch out for those dogs, those people who do evil, those mutilators who say you must be circumcised to be saved. For we who worship by the Spirit of God are the ones who are truly circumcised. We rely on what Christ Jesus has done for us. We put no confidence in human effort, though I could have confidence in my own effort if anyone could. Indeed, if others have reason for confidence in their own efforts, I have even more! I was circumcised when I was eight days old. I am a pure-blooded citizen of Israel and a member of the tribe of Benjamin—a real Hebrew if there ever was one! I was a member of the Pharisees, who demand the strictest obedience to the Jewish law. I was so zealous that I harshly persecuted the church. And as for righteousness, I obeyed the law without fault. I once thought these things were valuable, but now I consider them worthless because of what Christ has done. Yes, everything else is worthless when compared with the infinite value of knowing Christ Jesus my Lord. For his sake I have discarded everything else, counting it all as garbage, so that I could gain Christ and become one with him. I no longer count on my own righteousness through obeying the law; rather, I become righteous through faith in Christ. For God’s way of making us right with himself depends on faith. I want to know Christ and experience the mighty power that raised him from the dead. I want to suffer with him, sharing in his death, so that one way or another I will experience the resurrection from the dead! I don’t mean to say that I have already achieved these things or that I have already reached perfection. But I press on to possess that perfection for which Christ Jesus first possessed me. No, dear brothers and sisters, I have not achieved it, but I focus on this one thing: Forgetting the past and looking forward to what lies ahead, I press on to reach the end of the race and receive the heavenly prize for which God, through Christ Jesus, is calling us. (Philippians 3:1-14 NLT)
As a safeguard, Paul reviewed the basics with these believers. The bible is our safeguard both morally and theologically. When we read it individually and publicly in church, it alerts us to corrections we need to make in our thoughts, attitudes, and actions.
It is easy to place emphasis on religious effort than on internal faith, but God values the attitude of our hearts above all else. Don’t judge people’s spirituality by their fulfillment of duties or by their level of human activity. And, don’t think that you will satisfy God by feverishly doing his work. God notices all you do for him and will reward you for it, but only if it comes as a loving response to his free gift of salvation.
We have all done things for which we are ashamed, and we live in the tension of what we have been and what we want to be. Because our hope is in Christ, however, we can let go of past guilt and look forward to what God will help us become. Don’t dwell on your past, instead, grow in the knowledge of God by concentrating on your relationship with him now. Realize that you are forgiven, and then move on to a life of faith and obedience.
