Fire
Fire can reduce an entire building to ashes in a matter of minutes. The breathtaking power of fire is an appropriate parallel for the awe inspiring strength of  God. He appeared to Moses in a burning bush (see Exodus 3:2) and to the Israelites in a pillar of fire in the desert (see Exodus 13:21). But the Bible also cites instances in which fire is a literal instrument of God's judgment. Burning sulfur destroyed the Old Testament cities of Sodom and Gomorrah, and fire consumed the Israelites who disobeyed him in the desert. God has created a lake of fire for the eternal punishment of Satan and his followers.

The destructive qualities of fire make it an effective tool for purification. Fire can refine a substance like gold, which doesn't burn, by consuming foreign elements in it, so that only the pure gold remains. Scripture compares this purifying action to the work of God in the lives of Christians. God is working to eliminate impure thoughts and actions, leaving only the good that comes from him.

Fire represents the presence and power of the Lord.
