How do we know the doctrine of losing all for Christ is true?

The truth of the doctrine that calls believers to lose all for Christ can be seen in the life of the Apostle Paul, who experienced a radical change of heart after his encounter with Christ on the road to Damascus. His declaration in Philippians 3:7-8 illustrates this shift; he evaluates his previous achievements—heritage, law, and zeal—as worthless when compared to the glory of knowing Christ. This teaching echoes throughout Scripture, showing that any attempt to establish righteousness through human effort is futile. The doctrine reflects the core message of salvation by grace through faith (Ephesians 2:8-9), emphasizing that real value and fulfillment are found in Christ, who alone offers redemption. Therefore, the believer's call is to count all worldly gains as loss, echoing the reality of redemption and transformation through Jesus.
