Why is it significant that salvation originates with God?

The fact that salvation originates with God highlights His ultimate authority and sovereignty in the process of regeneration. As seen in John 1:1-4, all life, including spiritual life, comes from Him. This principle is crucial for understanding that salvation is entirely by grace and not by human effort or merit. God's initiative in regeneration ensures that no one can boast in their own works or decisions; rather, all glory is due to His unmerited mercy and grace, which He bestows on His elect.
