8 Yet indeed I also count all things loss for the excellence of the knowledge of Christ Jesus my Lord, for whom I have suffered the loss of all things, and count them as rubbish, that I may gain Christ
9 and be found in Him, not having my own righteousness, which is from the law, but that which is through faith in Christ, the righteousness which is from God by faith;
In verse 9 the phrase "and be found in Him" means to obtain Christ. When we put our faith in Jesus we should no longer strive to obtain things, or human status, we have obtained all we need in Christ Jesus. Our sole worth in life should now only be found in Him and nothing else, and like the apostle Paul we should count all things loss and focus on knowing Jesus. The apostle Paul before coming to Christ found his worth in how he lived his life. He described himself as a strict Pharisee, someone who was wrapped up in finding his own self worth and believed he was better than other people. But after receiving the gift of salvation he knew that his self worth was no longer to be found in what he had done, for he could not make himself right with God. He realized his worth was now found in who he was in Christ as a child of God and not how he had lived his life. Once you are born again don’t continue to live your life basing your worth on what you have done, but instead on who you are in Christ Jesus. Find yourself “in Christ” by counting all things as loss and focusing you life on getting to know Him. As you do, you will find the new you.
