How do we know that election is true in Christianity?

Election is grounded in the sovereignty of God, as described in passages such as Ephesians 1:4-5, which states, "He chose us in Him before the foundation of the world." This doctrine teaches that God predestines certain individuals to be saved, imparting His grace upon them and determining their place in His eternal kingdom. It emphasizes that salvation is a divine initiative, not a result of human choice or merit. This is further supported in Romans 8:28-30, where Paul elaborates on God's foreknowledge and predestination of believers. Hence, the doctrine of election is a profound assurance of God's sovereign grace.
