28 And the men of the town got up early in the morning, and they saw the altar of Baal broken down, and the holy tree which was by it cut down, and the ox offered on the altar which had been put up there. 29 And they said to one another, Who has done this thing? And after searching with care, they said, Gideon, the son of Joash, has done this thing. 30 Then the men of the town said to Joash, Make your son come out to be put to death, for pulling down the altar of Baal and cutting down the holy tree which was by it. 31 But Joash said to all those who were attacking him, Will you take up the cause of Baal? will you be his saviour? Let anyone who will take up his cause be put to death while it is still morning: if he is a god, let him take up his cause himself because of the pulling down of his altar. 32 So that day he gave him the name of Jerubbaal, saying, Let Baal take up his cause against him because his altar has been broken down.

(Read Judges 6:25-32)
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.
