What does the Bible say about good works in Christians?

In Philippians 1:6, the Apostle Paul assures believers that God, who began a good work in them, will continue to perform it until the day of Christ. This 'good work' refers to the process of regeneration, where individuals are born again by the Holy Spirit and therefore enabled to produce good works as a reflection of their faith and new nature. As believers, they are called to live in the newness of life which flows from this spiritual transformation. Good works cannot be separated from God's sovereign grace, as they are the fruit of His intricate work within us, rather than a means to earn salvation.
