How do we know God's covenant is for His elect?

The assurance that God's covenant is specifically for His elect is clearly outlined in various Scripture passages. In Ezekiel 36:22, God states that He acts for His own name's sake and for no other reason, indicating that the elect are not arbitrarily chosen but are part of His intentional design. Paul, in Ephesians 1:4-5, further adds that believers were chosen in Christ before the foundation of the world, confirming that God's selection is based on His purpose and grace, not on foreseen faith or actions.

This exclusivity of the covenant is also supported by the imagery of Israel as God's covenant people throughout the Old Testament. The language used in Ezekiel indicates that this covenant isn't extended to all humanity indiscriminately but to a specific people. Hence, understanding that God's elect are those written in the Lamb's book of life, as stated in Revelation 13:8, emphasizes His sovereign initiative in saving those He chose.
