Who's side are you on?

I got hit in the head with a frying pan this morning while sitting in first service at church it was Joshua 5 13-15
13When Joshua was by Jericho, he lifted up his eyes and looked, and behold,(O) a man was standing before him(P) with his drawn sword in his hand. And Joshua went to him and said to him, "Are you for us, or for our adversaries?" 14And he said, "No; but I am the commander of the army of the LORD. Now I have come." And Joshua(Q) fell on his face to the earth and worshiped and said to him, "What does my lord say to his servant?" 15And the commander of the LORD’s army said to Joshua,(R) "Take off your sandals from your feet, for the place where you are standing is holy." And Joshua did so.
I don't want God on "my" side I want to be on Gods side doing his will in my life. I can't tell you how many times I have screwed up Gods plan because I thought my way was better or faster.

Thanks Dave I needed this
