How do we know that God chooses those who will be saved?

The doctrine of God's sovereign choice is foundational in Reformed theology. Ephesians 1:4-5 states that God chose us in Christ before the foundation of the world, indicating that salvation is not based on our merit but solely on God’s sovereign will. Additionally, in the parable of the sower in Mark 4, we see that the different responses to the gospel highlight God's role in preparing hearts. Those who hear and believe are those whom God has called, demonstrating His active choice in the process of salvation. Ultimately, we understand that it is God’s grace that makes the difference between those who respond to His word and those who do not.
