Incense was burnt in the Temple, and animal sacrifices were roasted with fire. But fire is also a symbol in both OT and NT for an aspect under which God is made known—a ‘consuming fire’ (Heb. 12: 29). It is associated with God's wrath against sin, and the day of the Lord will see the purification of Israel by fire (Zech. 13: 9). Fire is also a symbol of the presence of God, as in the burning bush (Exod. 3: 2) and the appearance on Mount Sinai (Exod. 13: 21–2). The Holy Spirit descended on the apostles at Pentecost in the likeness of fiery tongues (Acts 2: 3).
