Sermons on Covenant Theology
In Hebrews 12:18-24 the author uses the figures of Mt. Sinai and Mt. Zion to highlight the differences between the Old Covenant and the New. The New Covenant is both more glorious and provides more sure access to God. Those who approached God in the Old Covenant did so with fear and trembling. Now through the blood of Christ we can approach with confidence.
Jeremiah 31:31-34 is a very important text for understanding the relationship between the Old Covenant and the New Covenant. Pastor Grasso explains the similarities and differences between the two as given in Hebrews 8 and other parts of the New Testament, showing that the New Covenant is the fulfillment of the Old, that the way of salvation was fundamentally the same between the two, and that the New is superior in terms of efficacy.
