Why is it important to believe that Jesus saves based on His grace?

The emphasis on salvation by grace, as articulated in Ephesians 2:8-9, underscores that it is God's unmerited favor rather than human works that brings about salvation. This is crucial because it shifts the focus from human effort, which would lead to boasting, to God's sovereignty and mercy, which ensures that salvation is a gift. This reflects the core tenet of sovereign grace theology, where God chooses whom He will save, and it is by His grace that any are called to eternal life. Therefore, recognizing the divine initiative in salvation deepens one's understanding of God's character and the nature of the relationship between the Savior and the saved.
