Knowing leads you out of darkness. Knowing for yourself is the only way you are going to free yourself from darkness.
To be a believer or a unbeliever is to live your life in total ignorance. But there is no power in the universe that can force you to live a life of ignorance. Those who are living in ignorance are doing so, of their own free choice.

God cannot force you to do anything nor can the devil. The things we do, we choose to do them ourselves. So if anyone knows God, it is because they choose to do so. Those who don't know God must examine what kind of choice they have made in this life.
