How do we know the doctrine of double predestination is true?

Double predestination is a doctrine that emphasizes God's sovereignty in the election of individuals to salvation or reprobation. This doctrine is firmly rooted in scriptures that affirm God's control over salvation, such as Romans 8:28-30, where Paul asserts that those God foreknew, He also predestined to be conformed to the image of His Son. The consistency of God's nature as just and merciful supports the idea that His sovereign choice is at the heart of both election and condemnation. Importantly, understanding this doctrine leads us to a clearer grasp of grace, emphasizing that salvation is purely the work of God rather than human effort.
