In my interpretation of these words, hope is a passive wish that something will come through eventually, but with the possibility that it won’t. If your drowning man hopes someone will come along when you are killed, he’s accepted and is prepared for the alternative scenario, all on his own. If you try, he’ll do anything and will keep sailing and the person will not come, he’s been told by default not and will turn around.

On the other hand, if he has faith that someone will come along, he is not ready to give up, he is sure that he’ll make it and base this certainty on any number of factors, beliefs, knowledge, etc. Mr. Johansson, “My dearest son, I am innocent that I am going to drop everything.” Why is it an active expectation?
