Different levels of guidance

Q: Is it correct to say that guidance is actually from Allah Ta'ala alone, and that when the Prophets gave us guidance, they themselves did not guide us, but it is Allah Ta'ala who guided us? Also, is it mentioned in the Quran that Allah Ta'ala told the Holy Prophet (sallallahu alayhi wasallam), "It is not you who guides them, it is Allah who guides"?
