In this lesson from Philippians 3, the Apostle Paul explains that the central pursuit of the Christian life is to know Christ deeply by experiencing His resurrection power, sharing in His sufferings, and becoming more like Him. Paul admits he has not yet reached full maturity, but like a runner, he presses forward with focused determination, refusing to be hindered by past successes, failures, or religious credentials. Paul’s “one thing” is to forget what lies behind and reach toward God’s goal for him—Christlikeness—while urging believers to do the same.
