What does Judges 6:39 mean?
While Gideon's name is associated with "valor" (Judges 6:12), his early depiction in the book of Judges is characterized by insecurity and fear (Judges 6:11, 17, 27). Despite seeing miracles and being empowered by the Holy Spirit (Judges 6:19–21; 34–35), he's dared to ask God to perform an extremely specific miracle to prove His will (Judges 6:36–37). God graciously complied, causing a wooly animal skin to appear wet in the morning, while the ground around it was dry.A reader might well wonder if Gideon was still hoping for an excuse not to engage in battle. Though he will come to be a renowned leader of armies (Judges 7:24–25; 8:28), the man asking God for signs here is not yet a leader, nor a soldier. The Lord has already provided more than enough evidence—Gideon has already asked for an absurdly unreasonable level of proof. To his credit, Gideon knows he's pushing his luck with God's patience. He sensibly begs God not to be angry as he makes yet another request—this time to invert the previous night's miracle.
It's challenging to realize that God does not rebuke Gideon for this request. In fact, Gideon is listed among those famous for obediently trusting God (Hebrews 11:32–34). The challenge is amplified by the way Scripture generally condemns "sign-seeking" as opposed to common sense obedience to God's revealed will (Matthew 12:38–39; 1 Corinthians 1:22–23). A possible answer lies in the very fear and hesitation Gideon expresses in his early appearances. Few people think of "bravery" when a large, strong man obeys a command to fight another strong man. For a small child, however, obedience to the same command requires greater faith, overcoming much greater anxiety. That Gideon is credited with faithful obedience—rather than being hard-headed—suggests he obeyed despite intense personal fear and anxiety. That God reacts with gracious reassurance, instead of the rebukes offered to others, implies the same.
This time, Gideon asks God to reverse the previous confirmation. This would dispel any chance that the first test was a natural fluke. Should the ground be wet, and the wool dry, that would be truly miraculous (Judges 6:40)
