If and when you preach through Judges, you will discover that God spent a lot of biblical real estate on the Gideon narrative. God gives tons of detail on Gideon versus Midian, probably because that contest functions as a paradigm for our salvation. Gideon is a highly unlikely military leader; his victory over the Midianites was a highly unlikely victory. That’s the point.
You’re familiar with how unsure Gideon was about God’s plan and how he asked God more than once to confirm the plan with a miracle (“the fleece”). Where’s his faith anyway?! It’s comforting to see how God did not chastise Gideon for his doubts. No lecturing; just confirming. Of course, Gideon’s example is not instruction for us to “go and do likewise.”
But the key to the narrative and its theology is God’s instruction to Gideon to whittle down his army, “lest Israel boast over me, saying, ‘My own hand has saved me.'” (cf. Judges 7:2). This is one of those examples of how the narrative provides a huge clue to meaning.
And be careful how you explain the Lord’s way of decreasing the size of Gideon’s army. God doesn’t tell us why the “lappers” are chosen, but not the “kneelers.” Whatever God’s reason, His intention was to take away any cause for Israel to boast in their strength. So contrary to many preachers’ explanations, the 300 who are selected are a sign of weakness, not strength. Plus, note that they take “trumpets” (v. 8, 22), not spears or bows. The soldiers were turned into fierce instrumentalists!
But God gives His people the victory over the Midianites. And it’s a great reminder of the fact that our salvation is all of God and none of us. We have a strong Savior who continually delivers us from overpowering forces that threaten to undue us. He graciously saves and sanctifies us. He does it all by Himself so we can only boast in the cross of Christ.
Preach well for sake of His reputation in the Church and in Christ Jesus (Ephesians 3:21).
