What does the Bible say about perseverance of the saints?

The Bible emphasizes that true believers will ultimately persevere in their faith and the pursuit of holiness, assured by God's sovereign grace. This is distinctly expressed in Scriptures like Romans 8:30, which outlines the process of salvation from predestination through glorification. As seen in Philippians 2:12-13, believers are called to work out their salvation while being assured that it is God who enables their will and actions to align with His good purpose. Therefore, the doctrine of perseverance highlights both God's sovereign work and the believer's responsibility to press on in faith and holiness.
