These three words are different in very important and significant ways.
All three (four) definitions are the first ones listed in The American College Dictionary, Random House 1962.
Acceptance – act of taking or receiving something offered.
Surrender – to yield (something) to the possession or power of another.
Resignation – act of resigning
Resign – to give up an office or position (often fol. by from).
Those three words, by definition, are not the same.
