How do we know that justification leads to glorification?

The assurance that justification leads to glorification is firmly rooted in Scripture, particularly in Romans 8:30, where the Apostle Paul outlines the golden chain of salvation: those whom God foreknew are predestined, called, justified, and glorified. This emphasizes that glorification is the inevitable conclusion of the salvation process initiated by God’s sovereign grace. As a part of the new covenant, believers are assured of their glorious transformation because it rests not on human action but on God’s unchanging promises and His sovereign will. Therefore, the security of glorification is guaranteed for all who are truly justified by faith in Christ alone.
