How do fruits of righteousness come about?

The fruits of righteousness come solely through Jesus Christ and the working of the Holy Spirit within believers. As affirmed in Philippians 1:11, these fruits are 'by Jesus Christ,' highlighting that no good work can originate from human effort alone. Instead, they flow from being united with Christ, much like branches drawing nourishment from a vine (John 15:5). The spiritual fruits are cultivated through faith in Christ, prayer, and reliance on the Holy Spirit, who empowers Christians to live lives that reflect the character of God. Therefore, understanding that our righteousness is not from ourselves, but from Christ, provides both encouragement and assurance in our Christian journey.
