What does 'Savior of the world' mean in the Bible?

In the New Testament, the phrase 'Savior of the world' signifies that Jesus' salvation is available to all humanity. John 4:42 states that Jesus is indeed the Savior of the world, which underscores the inclusiveness of the Gospel message. However, it is important to understand this through the lens of those who respond to His call. The doctrine of election emphasizes that while salvation is offered universally, it is personally applied to those whom God has chosen to save. This dual aspect of Jesus’ saviorhood teaches us that while His atoning work is sufficient for all, it is effectual only for the elect, those whom God has purposed to believe.
