my weakness is perfect

So I'm still going through The Good and Beautiful God and it is an amazing read!  The chapter I'm on talks about how we are sinners but now that Christ dwells in us sin reigns no more!  It discussed the verse 2 Corinthians 12:9--But he said to me, “My grace is sufficient for you, for my power is made perfect in weakness.” Therefore I will boast all the more gladly about my weaknesses, so that Christ’s power may rest on me.  I love this because it lets us know that even though we are weak God can use our crappy selves for good!  The mess and struggles we are going through will be used for His glory, what could be more beautiful and refreshing?  This makes me think that the ONLY thing perfect about us is our weaknesses.  Crazy I know.
