What does Philippians 3:12 mean?
Paul has just spoken about his future death and resurrection with Christ. Someday, he will be made complete and perfect before the Lord (Philippians 3:10–11). He begins a new section in this verse, starting with an important qualifying statement. Paul does not want his readers to think he saw himself as perfect and sinless. He is clear that his life is a work in progress (Romans 7). Paul has not yet been made like Christ, in a resurrected body, and has not yet reached the point of being without sin. This accomplishment is something which only happens when we are perfected in heaven.Instead of claiming to be perfect now, Paul continues to pursue becoming more like Christ. A Christ-like life is not a moment to achieve, but a goal to pursue. Paul knows he would never be perfect in this world, but instead made it his ambition to become increasingly like Christ in this life.
Philippians 3:12—4:1 explains the proper attitude Christians ought to have on the process of ''sanctification.'' This is the gradual, lifelong path of becoming more and more like Jesus. Our place in eternity is secure from the moment we trust in Christ, but it takes time to see our actions and attitudes change to be like His. Paul notes that he is not perfect, but encourages Christians to mimic his singular focus on pursuing Jesus. Paul also weeps for those who reject the gospel, a choice that will result in their destruction.
Paul details his impressive Jewish resume. None of his critics or challengers could boast the pedigree carried by Paul. He mentions this only to emphasize how little such things mean, next to faith in Christ. Paul's language here is sharp and to the point. He then explains how a Christian's focus ought to be purely on Christ, just as a runner concentrates on their goal in order to run effectively. Rather than looking to the past, or to ourselves, we ought to look forward, to an eternity with the Lord.
