What does 'for' mean in the sentence?

Question

At first, I understood the boldfaced for all as in spite of, but now I've found of after that, which made me confused. What does the last sentence mean?

The journey to discovering your authentic self promises to be the most rewarding adventure of your life. When you know yourself, you are free. You have a power and presence that radiates from deep within and shines out confidently into the world. You did not come into this life to suffer, to be manipulated and denied. Whatever binds you and keeps you from living your truth is false and can be shed. It takes courage to embrace your authentic self and live life on your own terms. Yet to be uniquely you, to listen within and love yourself for all of your weaknesses and missteps, is what your soul longs for.

Answer 1

You are correct, "for all (of) your weakness" means in spite of every bit of weakness you have.

all your weakness

all of your weakness

are slightly different ways of expressing the idea.

He ate all the cake.

He ate all of the cake.

The cake is gone in either case. The second, with of, presents the cake as something from which some or a piece can be taken.

all in the first expresses the idea "the entire thing".

all in the second expresses the idea "every bit of it".
