The following is from the Introduction by Rufus M. Jones to "The Power of Non-Violence" by Richard B. Gregg, Lippincott, 1934:

There is a remarkable story about Moses in ancient Hebrew legends. It tells how when Moses was going up the mountain to his death on Pisgah he asked Jehovah why it was not possible for him to be allowed to enter the Promised Land which he could see stretched out before his eyes. "You doubted me," Jehovah said to him, "but I forgave you that doubt. You doubted your own self and failed to believe in your own powers as a leader, and I forgave that also. But you lost faith in this people and doubted the divine possibilities of human nature. That I cannot forgive. That loss of faith makes it
impossible for you to enter the land of promise."

It is only a legend, but it suggests a profound truth. It is only those who believe in man and have faith and hope in the new and better world which man in co-operation with G-d can build here on earth that help to lead us toward the lands of promise.
