What was the main factor in Imam Khomeini’s progress and success?

The second point is that the main factor in the progress and success of our magnanimous Imam (r.a.) was his heartfelt and strong belief in a Quranic principle and truth. He believed in this principle from the bottom of his heart and he worked with all his power on this path. That Quranic principle is what has been pointed out and stressed in this holy ayah: "If you help the cause of Allah, He will help you and make firm your feet" [The Holy Quran, 47: 7] and many other ayahs. If you help God, God will help you too. If you take a step on the path of God, Allah the Exalted will help you take tens and hundreds of steps forward. This is a Quranic principle and it is a fact and a divine law. Helping God means helping His religion... Imam (r.a.) employed this Quranic truth for the sake of saving his country and his people. He helped God by sparking an uprising. And Allah the Exalted helped him as well and bestowed His blessings on his movement. When Imam (r.a.) took one step, Allah the Exalted responded by hundreds of steps.
