Joshua 10

Joshua 10:8: 
The Lord said unto Joshua, Fear them not: for I have delivered  them into thine hand; there shall not a man of them stand before thee

God pronounced victory even before Joshua went into battle. He said, "The victory is already won! Not one of these enemy soldiers will be left standing after the battle. Now, go and fight, knowing I have promised you the victory!" That is the message of the cross! The victory has already been won for us
