Acceptance, Surrender, Resignation

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.
