Paul's radical conversion when he met Jesus on the road to Damascus changed everything about his life. Before Christ, he was a zealous Pharisee who strictly kept the law and found his identity in being a Hebrew of Hebrews. However, when Christ entered his life, the things he used to consider as gains, he now counted as losses. He used to think that his religious credentials (see Phil. 3:4–7) gave him value in God's eyes, but after coming to Christ, he realized that really, they were simply a hindrance. Now, he considered everything worthless because of how great it is to know Jesus. He didn't depend on his own attempts to be righteous anymore but rested in the righteousness of Christ that was imputed to him by God through faith in Christ and His death and resurrection (See 2 Cor 5:21).
