6:40 dew on all the ground. Judges 6:36-40 provide the source of the well-known expression, “putting out a fleece,” as a method of determining God’s will. The first miracle–dew on the fleece with the ground dry around it–involved a providential acceleration of the natural tendency of fleece to assimilate moisture from the atmosphere. The second–the fleece dry with dew all around–was a more certain sign, involving an actual reversal of the natural process. This provided clear proof to Gideon that God was, indeed, leading Him and was well able to fulfill His promise. This was a very special case, however, warranting special supernatural intervention by God in His natural processes. God normally reveals His will to those who desire to know and follow it through His word and by providential circumstances. Note the promise of guidance in such passages as Romans 12:1,2; I John 5:14,15; Proverbs 3:5,6.
