How do we know that election of grace is true?

Election is the doctrine that God has chosen a remnant of grace to be saved, drawing directly from passages such as Isaiah 1:9 and Romans 9:10-16. It emphasizes the point that God's choice is not based on any foreseen actions or merits of individuals, but solely on His sovereign will. In the sermon, it is articulated that if God had not elected a remnant, all would be lost like Sodom and Gomorrah. This reinforces the security of salvation, as it rests entirely on God's decision and purpose rather than human effort.
