The Lord graciously answered Gideon's request for additional signs that God was with him. Gideon did not need to request these signs; God had already promised to help him (vv. 14, 16) and had given him a sign (v. 21). Notwithstanding, Gideon's faith needed some added support, and God provided this without reproof (cf. James 1:5).
"The remarkable thing is that God responds to his tests. He is more anxious to deliver Israel than to quibble with this man's semipagan notions of deity."154
"Gideon's fleece is not a sign of faith. It is the opposite. It is not a search for God's will. It is a desperate grasp for security by one who knows clearly what that will is but who is reluctant to do it."155
Perhaps Gideon used a woolen fleece because it was handy. He asked God to cause the dew to settle on the fleece that night but not on the surrounding ground. In the morning he discovered that is what God had done. Gideon may have concluded that he had asked the wrong thing since wool attracts dew. In any case he asked God to let the dew fall on the ground but not on the fleece the next night. God did this too. Thus this double demonstration that God was indeed with him and would grant him victory as He had promised strengthened Gideon's faith.
"But Gideon's fleece was not about discovering the will of God, and his actions are not to be taken as a normative paradigm for discovering the will of God. It was about stubborn resistance to what one knows clearly to be God's will."156
Some students of this story have seen a deeper meaning in these signs than is immediately apparent.
"Dew in the Scriptures is a symbol of the beneficent power of God, which quickens, revives, and invigorates the objects of nature, when they have been parched by the burning heat of the sun's rays. The first sign was to be a pledge to him of the visible, tangible blessing of the Lord upon His people, the proof that He would grant them power over their mighty foes by whom Israel was then oppressed. The woollen fleece represented the nation of Israel in its condition at this time, when God had given power to the foe that was devastating its land, and had withdrawn His blessing from Israel. The moistening of the fleece with the dew of heaven whilst the land all round continued dry, was a sign that the Lord God would once more give strength to His people from on high, and withdraw it from the nations of the earth. Hence the second sign acquires the more general signification, that the Lord manifested himself even in the weakness and forsaken condition of his people, while the nations were flourishing all around' (O. v. Gerl.) . . . ."157
Did God intend the dew, the fleece, and the ground to represent these things? Whether He did or not it is clear that these two miraculous demonstrations of God's presence and power strengthened Gideon's faith. Gideon was now ready to lead the Israelites against their foes.
Note four things that God used to prepare Gideon in this chapter. First, Gideon met the preincarnate Christ. Second, he committed himself to following Yahweh. Third, he obeyed the Lord by taking a public stand for Him relying on His promises. Fourth, the Holy Spirit gave Gideon supernatural power. When the people God calls to Himself respond positively by committing themselves to Him and standing up for Him, He strengthens their faith so He can use them in greater ways. His ability can overcome the inability of His servants if they rely on His promises even though their faith may be weak.
"All the judges except Abimelech countered a foreign threat, but only in the case of Gideon is there an extensive personal interaction between the judge and the Lord. This observation suggests that the narrative provides more than simply a victory account for future generations of Israel's defeat of Midian. While it is true that Samson offered up a few quick prayers, only in the case of Gideon is there a focus on the judge's faith and his coming to grips with the Lord's call on his life."158
