How do we know God's choice is sovereign?

The sovereignty of God in His choices is underscored through His election of individuals like Jacob. In Romans 9:11-13, it is revealed that God's love and election are not based on human merit or actions but on His own will and purpose. Jacob is chosen despite his flaws and struggles, emphasizing that God's grace operates independently of human effort. This sovereign election illustrates that salvation is entirely God's work, affirming the historic Reformed understanding of unconditional election and the assurance that He will complete the work He begins in His chosen ones.
