Let/May

[wowenglish1]

I wonder if there is a subtle difference in meaning between "1" and "2",
if no, I would like to know which sentence is more polite.
1. Let me help you.
2. May I help you.

The first is not a question, it's a demand, the second is a question and should have a question mark. "May I help you?" is a polite question.

I have a question on these same words, so I'm not making make another thread.
When I want to express a wish, which is better:
Let it stop raining.
May it stop raining.

Let the power be with you.
May the power be with you.

Let your days be merry.
May your days be merry.

My thought is that imperative let is more like an order and may is more like a wish. Am I right?

Yes, "may" is better for expressing a wish.
