How do we know that God chose His people before creation?

The doctrine of election is central to Reformed theology and is articulated in various scriptures. In Ephesians 1:4, it is affirmed that God chose us in Christ before He even created the world. This teaching underscores the absolute sovereignty of God and His initiative in salvation, which was not based on our actions or decisions but entirely on His gracious will. Romans 8:29-30 further elaborates this by explaining the chain of salvation where God foreknows, predestines, calls, justifies, and glorifies His people, solidifying the assurance that our salvation is completely dependent upon God’s eternal plan.
