Philippians 3:3, 7-8

for we [who are born-again have been reborn from above—spiritually transformed, renewed, set apart for His purpose and] are the true circumcision, who worship in the Spirit of God and glory and take pride and exult in Christ Jesus and place no confidence [in what we have or who we are] in the flesh

But whatever former things were gains to me [as I thought then], these things [once regarded as advancements in merit] I have come to consider as loss [absolutely worthless] for the sake of Christ [and the purpose which He has given my life]. But more than that, I count everything as loss compared to the priceless privilege and supreme advantage of knowing Christ Jesus my Lord [and of growing more deeply and thoroughly acquainted with Him—a joy unequaled]. For His sake I have lost everything, and I consider it all garbage, so that I may gain Christ
