Rom 7:18 For I know that in me (that is, in my flesh,) dwelleth no good thing: for to will is present with me; but how to perform that which is good I find not.

I love this passage because of many of the struggles I have had in life. I know the good but how to find out the way through some struggles, well, you just seem to grope your way through them as sinner and saint. St. Paul understood that. That comforts me.
