Why is grace essential in sovereign grace theology?

In sovereign grace theology, grace is foundational because it signifies God’s unmerited favor towards a sinful humanity. Salvation is viewed as a divine gift that cannot be earned or maintained through human works (Romans 11:6). The doctrine of TULIP particularly emphasizes that it is solely by God's grace that the elect are saved, in spite of their inherent wickedness. The story of Tamar serves as a remarkable illustration of this principle. Tamar's situation reflects the idea that human efforts are inadequate in achieving righteousness; rather, it is God's grace that accomplishes salvation amidst deep sin and failure. This concept is central in reaffirming that salvation is entirely the work of God, making grace indispensable to our understanding and appreciation of the gospel.
