How do we know that grace is sovereign and free?

The sovereignty and freeness of grace are poignantly illustrated in the calling of Levi, the publican, in Mark 2:14. Jesus’ choice to call Levi, who held a despised position among his people, signifies that God's grace operates independently of human worthiness or righteousness. This theme aligns with the overarching biblical narrative that emphasizes God's sovereign choice in election, as seen in 1 Corinthians 1:26-29, where God chooses the foolish and weak to confound the wise. Such grace cannot be earned; it is a divine initiative, ensuring that no flesh can boast of personal righteousness before God, demonstrating that salvation is entirely a work of grace, not determined by human works or status.
