As I read this I was drawn to the fact that Gideon was fearful. The Lord told him "if you are afraid to go down, go down to the camp with Purah your servant" (v. 10) and Gideon did just that, he took his servant and went. Then once they were there God did exactly what He promised, "you shall hear what they say; and afterward your hands shall be strengthened to go down against the camp." (vs. 11) God showed them, through the the account of the loaf of barley bread, that victory was assured.
This made me think of the many times in my life that God allowed friends to come alongside of me during trying times. When I was afraid. Then with them there, for support, God showed through His Word and other ways that victory would come and it all depended on Him. Praise His Name for the victory He gives!
