Not at all...that doesn't mean he thinks everything he does is what God has instructed him to do...he means that he prays to listen for God's guidance. Sometimes, we think we hear his guidance, but are really just trying to push our own agenda. The humility comes when you hear what you don't want to do, but are sure is right.
I am sure this happened with the president when he ordered us into Iraq. He knew that men would die on both sides, and that it could cost him the presidency.
Well it's one thing to pray for God's guidance...
It's quite another to say that God speaks "through" him.
