How do we know that God's grace is assured in Christ?

The assurance of God's grace in Christ stems from the eternal covenant established before creation, as described in 2 Samuel 23:5. This covenant secures salvation for all who believe, independent of human effort or will. The efficacy of Christ's death and resurrection demonstrates that He fulfilled the law's demands, making it possible for God to justify the ungodly. This assurance is encapsulated in the belief that salvation is not based on one’s actions but on Christ’s merit, reinforcing the importance of faith and reliance on divine grace.
