Abraham’s surrender of personal ambitions in behalf of Melchizedek is why three celestial beings appeared to him.  Man many times bows down before the idols of his selfish ambitions.  Thousands of men allow ambition to enslave them to debt. 
Few mortals ever dare to draw anything like the sum of personality credits established by the combined ministries of nature and grace. The majority of impoverished souls are truly rich, but they refuse to believe it.  Forceful ambition, intelligent judgment, and seasoned wisdom are the essentials of material success.  Ambition is futile without an audience to parade before.  Jesus repeatedly dashed his apostles’ ambitions. 
Every human being should remember: Many ambitions to excel which tantalize mortals in the flesh will not persist with these same mortals in the morontia and spirit careers, but before ascending mortals leave the local universe to embark upon their spirit careers, they will be satiated respecting every intellectual, artistic, and social longing or true ambition.  Ambitions may thwart maternal instinct.  Ambition is opposed by animal indolence.  Spirit-born individuals are so remotivated in life that they can calmly stand by while their fondest ambitions perish and their keenest hopes crash.  It is forever true: What we begin in time we will assuredly finish in eternity—if it is worth finishing. 
Belief in charms did much to destroy personal ambition and initiative.  Mortal desire and human ambition were virtually destroyed by Vedic doctrines.  Buddhists taught all human striving distasteful. 
Ambition is dangerous until it is fully socialized. You have not truly acquired any virtue until your acts make you worthy of it.  Ambition can become dangerous when it is once wholly wedded to self-seeking and supremely motivated by sullen and long-suppressed vengeance.
