Fire will only keep burning as long as it has fuel and oxygen, but when it runs out of either, it will go out. Now, God is eternal, but the power He provides us is not something we can just take for granted as always being there. We must tend the fire in order to keep it burning. There’s a great lesson we can learn from the fire on the altar of the temple. God gave these instructions in Leviticus 6:12: “The fire on the altar must be kept burning; it must not go out. Every morning the priest is to add firewood and arrange the burnt offering on the fire.”
