How do we know the doctrine of self-control is true?

The doctrine of self-control, or 'dominion over oneself,' is not merely a moralistic principle but a command rooted deeply in Scripture. Paul illustrates this in Galatians 5:22-23, noting that self-control is among the fruits of the Spirit. This indicates that genuine self-control comes from the transformative work of the Holy Spirit in a believer's life. It is not about external constraint but internal empowerment to live righteously. Moreover, the Apostle Paul in 1 Corinthians 9:24-27 speaks of exercising control over one's body, pressing the importance of self-denial for the sake of heavenly rewards, affirming that maintaining discipline and self-control aligns with spiritual maturity and the pursuit of Christ.
