Verse 1-6 — Israel's sin was renewed, and Israel's troubles were repeated. Let all that sin expect to suffer. The Israelites hid themselves in dens and caves; such was the effect of a guilty conscience. Sin dispirits men. The invaders left no food for Israel, except what was taken into the caves. They prepared that for Baal with which God should have been served, now God justly sends an enemy to take it away in the season thereof.
Verse 7-10 — They cried to God for a deliverer, and he sent them a prophet to teach them. When God furnishes a land with faithful ministers, it is a token that he has mercy in store for it. He charges them with rebellion against the Lord; he intends to bring them to repentance. Repentance is real when the sinfulness of sin, as disobedience to God, is chiefly lamented.
Verse 11-24 — Gideon was a man of a brave, active spirit, yet in obscurity through the times: he is here stirred up to undertake something great. It was very sure that the Lord was with him, when his Angel was with him. Gideon was weak in faith, which made it hard to reconcile the assurances of the presence of God with the distress to which Israel was brought. The Angel answered his objections. He told him to appear and act as Israel's deliverer, there needed no more. Bishop Hall says, While God calls Gideon valiant, he makes him so. God delights to advance the humble. Gideon desires to have his faith confirmed. Now, under the influences of the Spirit, we are not to expect signs before our eyes such as Gideon here desired, but must earnestly pray to God, that if we have found grace in his sight, he would show us a sign in our heart, by the powerful working of his Spirit there, The Angel turned the meat into an offering made by fire; showing that he was not a man who needed meat, but the Son of God, who was to be served and honoured by sacrifice, and who in the fulness of time was to make himself a sacrifice. Hereby a sign was given to Gideon, that he had found grace in God's sight. Ever since man has by sin exposed himself to God's wrath and curse, a message from heaven has been a terror to him, as he scarcely dares to expect good tidings thence. In this world, it is very awful to have any converse with that world of spirits to which we are so much strangers. Gideon's courage failed him. But God spoke peace to him.
Verse 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.
Verse 33-40 — These signs are truly miraculous, and very significant. Gideon and his men were going to fight the Midianites; could God distinguish between a small fleece of Israel, and the vast floor of Midian? Gideon is made to know that God could do so. Is Gideon desirous that the dew of Divine grace might come down upon himself in particular? He sees the fleece wet with dew to assure him of it. Does he desire that God will be as the dew to all Israel? Behold, all the ground is wet. What cause we sinners of the Gentiles have, to bless the Lord that the dew of heavenly blessings, once confined to Israel, is now sent to all the inhabitants of the earth! Yet still the means of grace are in different measures, according to the purposes of God. In the same congregation, one man's soul is like Gideon's moistened fleece, another like the dry ground.
