How do we know Arminianism is contrary to Scripture?

Arminianism proposes that human free will is the determiner of salvation, which directly contradicts scriptural teachings on God’s sovereign choice and grace. Romans 9 presents a clear biblical argument that God has mercy on whom He chooses and hardens whom He wills. Such passages challenge the Arminian perspective by showcasing God’s ultimate authority over salvation and His purpose, which is not contingent on human will but rather on His divine will. Furthermore, the historic Reformed perspective underscores that Scripture reveals humanity’s total depravity, indicating our inability to choose God without His intervening grace, thereby highlighting the essential need for the doctrine of predestination.
