How do parables relate to the sovereignty of God?

Parables highlight the sovereignty of God by illustrating His authority to give understanding or to withhold it as He pleases. In Matthew 13, Jesus explains to His disciples that knowledge of the kingdom is given to them but not to others. This reflects the idea that salvation and understanding are ultimately gifts from God, emphasizing that it is not about human decision but divine choice. As outlined in Romans 9, God has the sovereign right to show mercy to whom He will, reinforcing the idea that understanding spiritual truths is an act of God's grace.
