How do we know the doctrines of sovereignty and election are true?

The biblical doctrines of sovereignty and election are deeply rooted in Scripture. For instance, Romans 9 explicitly discusses God's sovereignty in choosing whom He will save. It asserts that God's purpose in election stands firm, independent of human actions. Additionally, Ephesians 1:4-5 speaks of God choosing us in Christ before the foundation of the world, granting us adoption as His children according to His will. These passages emphasize that God's sovereignty is foundational to our understanding of salvation. The unfolding of the historical narrative of Christ’s coming fulfills God's predetermined plan, illustrating His sovereign rule over all creation and His intention to redeem His elect.
