That's a lot to ask. But it is something attainable. While such faith is attainable, it is not easy to come by. It takes more than a one-time statement of belief. It's more than some well-meaning mumbled prayers during the hard times.
Faith is a way of life.
Faith is a daily commitment to turn to G-d and listen for His voice and believe what He says. We will stumble. That is certain. I may falter in my step, but never beyond Your reach. G-d is not limited by our failings.
