The following excerpts are from The Game of Life and How to Play It by Florence Scovel Shinn.  Any emphasis is original.

Most people consider life a battle, but it is not a battle, it is a game.  It is a game, however, which cannot be played successfully without the knowledge of spiritual law, and the Old and New Testament give the rules with wonderful clearness.  Jesus Christ taught that it was a great game of Giving and Receiving. (p. 7)

There is always plenty on man’s pathway; but it can only be brought into manifestation through desire, faith or the spoken word.  Jesus Christ brought out clearly that man must make the first move.  

“Ask, and it shall be given you, seek and ye shall find, knock and it shall be opened unto you.”  (Mat. 7:7)  

In the Scriptures we read:  “Concerning the works of my hands, command ye me.”  

Infinite Intelligence, God, is ever ready to carry out man’s smallest or greatest demands.  Every desire, uttered or unexpressed, is a demand.  We are often startled by having a wish suddenly fulfilled. (p. 12)

**** 

Nothing stands between man and his highest ideals and every desire of his heart, but doubt and fear.  When man can “wish without worrying” every desire will be instantly fulfilled. (p. 13)

The records of Health, Wealth, Love and perfect Self-Expression, [t]his is the square of life, The Game completed. (p. 14) 

**** 

As man opens his mind to subjectivity, he becomes a target for destructive forces.  The psychic plane is the result of man’s mortal thought, and is on the “plane of opposites.”  He may receive either good or bad messages.  

The science of numbers and the reading of horoscopes keep man down on the mental (or mortal) plane, for they deal only with the Karmic path…. 

It takes a very strong mind to neutralize a prophecy of evil. (p. 71) 

  ****

As man becomes spiritually awakened he recognizes that any external inharmony is the correspondence of mental inharmony.  If he stumbles or falls, he may know he is stumbling or falling in consciousness. (p. 72) 

**** 

God’s will be done, not man’s; God’s pattern, not man’s pattern, is the command we find running through all the scriptures, and the Bible is a book dealing with the science of the mind. It is a book telling man how to release his soul (or subconscious mind) from bondage.  

The battles described are pictures of man waging war against mortal thoughts.  “A man’s foes shall be they of his own household.”  Every man is Jehoshaphat, and every man is David, who slays Goliath (mortal thinking) with the little white stone (faith). (p. 77) 

**** 

The simple rules [to winning the game of life] are fearless faith, nonresistance and love! 

May each reader be now freed from that thing which has held him in bondage through the ages, standing between him and his own, and “know the Truth which makes him free”—free to fulfill his destiny, to bring into manifestation the “Divine Design of his life, Health, Wealth, Love and Perfect Self-Expression.”  “Be ye transformed by the renewing of your mind.”  (p. 93)
