What does the Bible say about the everlasting covenant of grace?

The Bible reveals that the everlasting covenant of grace is a direct testament to God's mercy and unmerited favor towards humanity. This covenant was established with figures like Abraham who was called out from idol worship, not because of any goodness in him but purely by God's sovereign choice. In Deuteronomy 7:7-8, we understand that God's choice of Israel was not based on their multitude or righteousness but on His love and the promises made to their forefathers. This covenant underscores the truth that salvation is inherently a work of God alone, affirming the doctrine that we are saved by grace through faith, and not of ourselves, as stated in Ephesians 2:8-9.
