In this verse, the author of Hebrews is drawing a vivid contrast between the experiences of the Israelites at Mount Sinai and the new covenant established through Jesus Christ. Mount Sinai, where the law was given, was a place of awe and fear, marked by physical manifestations like fire, darkness, and storm. These elements symbolized the holiness and power of God, which was unapproachable and overwhelming to the people. The experience at Sinai was one of distance and fear, where the people were warned not to touch the mountain lest they die.
In contrast, the new covenant invites believers to Mount Zion, a spiritual mountain representing the heavenly Jerusalem, where God’s presence is accessible through Jesus. This new relationship is characterized by grace, mercy, and love, rather than fear and trembling. The emphasis is on a personal and intimate connection with God, made possible through faith in Christ. This shift from fear to grace encourages believers to draw near to God with confidence, knowing they are welcomed into His presence as beloved children.
