Faith is a paradigm through which a person sees reality. We know that reality is form, and form determines content. You are what you believe in, because you see it and what you see defines you. To get out of a vicious circle, you need a key. The key is hope.
When God sees human suffering, God wants to save a person, but the salvation of a drowning person is in the hands of the drowning person himself. A drowning man needs faith to save himself, and faith is the movement of his own hands and feet. God helps the walking, the crawling, but not the lying or running.
It is dangerous to protect a person from Vice from the outside. You will protect him from the lesser evil, and he will be the victim of the greater one. The lesser evil protects man from the greater one. A person can save himself from Vice only, an attempt to save him from the outside and by force will only aggravate the situation.
