Flesh retains a powerful propensity to worship that which is not God. Even the aged John, unquestionably mature in his faith, nearly succumbed to the temptation to drop his focus from God to a lesser one—and this at the climax of visions of the glory of God such as no man had ever seen! It was not because he mistook the angel for God, but because he was moved by his powerful visions and the impressive presence of the angel. The point is that even in the midst of the worship experience, it is possible to lose focus on God Himself and begin to worship the experience, the messenger of God.
