"And it came to pass, when Joshua was by Jericho, that he lifted up his eyes and looked, and, behold, there stood a man over against him with his sword drawn in his hand: and Joshua went unto him, and said unto him, Art thou for us, or for our adversaries? And he said, Nay; but as captain of the host of the LORD am I now come. And Joshua fell on his face to the earth, and did worship, and said unto him, What saith my lord unto his servant? And the captain of the LORD'S host said unto Joshua, Loose thy shoe from off thy foot; for the place whereon thou standest is holy. And Joshua did so." (Jos 5:13-15 AV)
How many times do we act as if the LORD is doing our bidding against those we oppose? The LORD is not a Calvinist. He is not a member of Calvary Chapel. He does not place any allegiance with the Assemblies of God. He is not a Christian. Who and what He is can be described as Holy. Note Joshua's question and the LORD's reply of no. The opposing question could be assumed here (with some risk). Is He against us? I believe He would answer again , "nay" but our response had better be the same.
