25 Now it came to pass the same night that the Lord said to him, "Take your father's young bull, the second bull of seven years old, and tear down the altar of Baal that your father has, and cut down the wooden image that is beside it; 26 and build an altar to the Lord your God on top of this rock in the proper arrangement, and take the second bull and offer a burnt sacrifice with the wood of the image which you shall cut down." 27 So Gideon took ten men from among his servants and did as the Lord had said to him. But because he feared his father's household and the men of the city too much to do it by day, he did it by night. 28 And when the men of the city arose early in the morning, there was the altar of Baal, torn down; and the wooden image that was beside it was cut down, and the second bull was being offered on the altar which had been built. 29 So they said to one another, "Who has done this thing?" And when they had inquired and asked, they said, "Gideon the son of Joash has done this thing." 30 Then the men of the city said to Joash, "Bring out your son, that he may die, because he has torn down the altar of Baal, and because he has cut down the wooden image that was beside it." 31 But Joash said to all who stood against him, "Would you plead for Baal? Would you save him? Let the one who would plead for him be put to death by morning! If he is a god, let him plead for himself, because his altar has been torn down!" 32 Therefore on that day he called him Jerubbaal, saying, "Let Baal plead against him, because he has torn down his altar."

See the power of God's grace, that he could raise up a reformer; and the kindness of his grace, that he would raise up a deliverer, out of the family of a leader in idolatry. Gideon must not think it enough not to worship at that altar; he must throw it down, and offer sacrifice on another. It was needful he should make peace with God, before he made war on Midian. Till sin be pardoned through the great Sacrifice, no good is to be expected. God, who has all hearts in his hands, influenced Joash to appear for his son against the advocates for Baal, though he had joined formerly in the worship of Baal. Let us do our duty, and trust God with our safety. Here is a challenge to Baal, to do either good or evil; the result convinced his worshippers of their folly, in praying to one to help them that could not avenge himself.
