Fire showed the Lord's presence (Exodus 9:23; 19:18; 40:38; Deuteronomy 4:24; 2 Chronicles 7:1; Isaiah 66:15; Amos 7:4), which could have been lightning (see Psalm 18:12–13; Ezekiel 1:13–14; Zechariah 9:14). The contest aimed to prove if Baal, the Canaanite storm god, or the God of Israel was the true God. Only the true God could ignite the wood (see Leviticus 9:24).
