Do The Trick

[namsteven]

Dear Teachers,

a. It will do a little good to try to persuade them.
- “It will do a little good” means “it will probably work”, right?

b. Whatever religion you are led to, you need to be led by your own desire, not by false persuasion. That just doesn’t do the trick.
- What does “do the trick” mean in this sentence”?

Thanks a bunch

a- It sound to me as though it should be 'it will do little good', which means it has little or no chance of succeeding.
b- Meet the requirements/standards- false persuading someone to follow a religion is not a genuinely religious view- a person should follow out of real belfief and understanding, not lies
