Off the top of my head, I can think of at least two ways that courage plays out in our lives.
~ I am afraid to do something (e.g. talk before a large crowd) but in spite of the fear I go ahead and do it.
Here fear co-exists side by side with courage. And what happens here in fact involves courage. I after all went ahead and gave a talk.
~ I am afraid to do something but then pray, reason or talk to someone about the thing that I fear and courage arises and fear disappears.
In this case, the fear is either completely driven out or becomes displaced in good measure. For the most part what remains is courage.
It seems that something of a similar sort is at work with weakness and strength, although the way it plays out is different.
~ C.S. Lewis was horrible at math. He flunked his entrance exams and such. He could appreciate math, but just could not do it. It was his weakness. Here is the thing though… what if Lewis was good at manage math and had gone on to become an engineer or something? Then the world would never have seen Narnia or Perelandra and so on. There would have been no Mere Christianity or The Abolition of Man. What a loss that would all have been!
And yet Mathematics remained his weakness throughout his life and co-existed side by side with his strength in writing to develop. In fact this weakness paved the way for him to develop his strength.
~ The C.S. Lewis example falls under this also in the sense of being displaced – to the very margins. However I am also thinking that there are cases where the weakness is driven out by a strength. Like you work on that weakness such as being lousy at basketball or cricket or whatever.
~ Finish this later.
