How do we know that God chooses some people to be saved?

The doctrine of election is clearly articulated in passages like Ephesians 1:4-5, where it states that God chose us in Christ before the foundation of the world. This choice is not based on any foreseen merit on our part but is according to His will and good pleasure. Romans 8:29 also affirms this truth, stating that those whom God foreknew, He predestined to be conformed to the image of His Son. These scriptures provide a solid foundation for understanding the sovereign grace of God in salvation, demonstrating that it is solely His grace that saves us, not our efforts or decisions.
