It means God has sovereignly selected certain individuals for salvation based on His grace and purpose.
The doctrine of divine election reveals that God has chosen a specific people for Himself before the foundation of the world, as echoed in Ephesians 1:4. This selection is not based on anything inherent in the individuals but entirely on God's mercy and grace. Romans 9 also discusses how God chooses whom He will have mercy on. This aspect of God’s nature emphasizes His sovereignty and the assurance that those whom He chooses are secure in their salvation through Christ. This understanding should give Christians confidence in God's plan and purpose, affirming that salvation is God's work from beginning to end and is offered freely to His chosen ones.
