What does 'great salvation' mean in a Christian context?

'Great salvation' encompasses the depth and breadth of the deliverance God offers to His elect through Christ. This salvation includes freedom from sin, the satisfaction of God's justice through Christ's sacrifice, and the promise of eternal life. It is not just a mere physical deliverance, as illustrated in the Exodus story, but a profound spiritual redemption that transforms believers and grants them access to all spiritual blessings. In light of God's sovereign grace, this salvation assures us that it is certain and everlasting, thereby emphasizing its greatness both in scope and effect.
