Hebrews 8:12 contains one of the most precious promises of the New Covenant: "For I will be merciful to their unrighteousness, and their sins and their lawless deeds I will remember no more."

This sermon examines the foundation of Christian forgiveness and assurance by exploring God's covenant mercy through Jesus Christ. Drawing from Jeremiah's prophecy of the New Covenant, the Day of Atonement in Leviticus, Psalm 32, Romans 3, and Hebrews 8, this message demonstrates how Christ's atoning sacrifice fully satisfies God's justice and secures complete forgiveness for His people.

The sermon explains the biblical meaning of unrighteousness, sin, and lawlessness, showing how every category of guilt is removed through the finished work of Christ. It also explores the doctrines of justification by faith, propitiation, imputation, and assurance of salvation, revealing why believers can rest confidently in God's promise to remember their sins no more.

Whether you are struggling with guilt, seeking assurance, or wanting a deeper understanding of the New Covenant, this message points to the sufficiency of Christ's sacrifice and the glory of God's saving grace.
