Out of chaos often comes the greatest creativity. And the only thing that can endure deep doubt is faith. You will not allow yourselves to go into the deeper levels of doubting without, in fact, a very strong faith.
Those who can endure great doubt, in my experience, have been those who rise to great faith. Faith gets purified every time you go through the cycle of doubt and failure, saying, “Why do I believe this? Do I believe this at all? What do I base my life on?” On this wheel of fortune just about everything is purified: self-image, God-image, worldview.
