Judges 6:29 They said to one another, “Who has done this thing?” When they inquired and asked, they said, “Gideon the son of Joash has done this thing.”
Judges 6:30 Then the men of the city said to Joash, “Bring out your son, that he may die, because he has broken down the altar of Baal, and because he has cut down the Asherah that was by it.”
Judges 6:31 Joash said to all who stood against him, “Will you contend for Baal? Or will you save him? He who will contend for him, let him be put to death by morning! If he is a god, let him contend for himself, because someone has broken down his altar!”
Judges 6:32 Therefore on that day he named him Jerub-Baal, saying, “Let Baal contend against him, because he has broken down his altar.”

The verse centers on "joash", "said", "stood", "against", "contend", "baal", and "save". It is saying that the verse draws attention to "joash" and "said", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 30's "Then the men of the city said..." into verse 32's "Therefore on that day he named him...", so "joash" and "said" belong inside that flow. In Judges context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "joash" and "said" with trust shaped by these words, not by a vague optimism outside the passage.
