Blood, Fire, and Water

Blood, fire, and water seem to be a theme of elements that God uses for significant purposes. In the temple, in the New Testament, etc. I was reading again last night the scene between Elijah and the prophets of Baal. In his prayer before the altar, Elijah prays for God to take action in part so that the people might know that he has done these things according to His command. He had just rebuilt the altar and placed a sacrifice on it (blood), and then dumped water on it (water). After the prayer God devours the sacrifice, wood, altar (these were stones!), soil! and water through...fire. The three elements. I'm sure the water that was poured on the sacrifice was in part to drive home the point that this was indeed fire from God that was powerful and even a soggy sacrifice couldn't hinder Him. But, I also find it interesting that God used these three elements once again during a crucial/significant time of turning the hearts of Israel back to Him once again.
