What does the Bible say about Christ's good work?

In Philippians 1:6, Paul assures us that the good work which Christ began in us will be completed until the day of Christ. This encompasses the transformative nature of salvation, where Christ, as the author and finisher of our faith, instills in believers the ability to bear righteous fruit. This fruit is born of grace and is meant to glorify the Lord Jesus Christ, rather than stemming from our own sinful nature, as highlighted in John 15:5, where Christ emphasizes that without Him, we can do nothing.
