Hebrews 12:18-24

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.
