wounds of a friend

"If, while we seek to be justified in Christ, it becomes evident that we ourselves are sinners, does that mean that Christ promotes sin? Absolutely not! If I rebuild what I destroyed, I prove that I am a lawbreaker. For through the law I died to the law so that I might live for God." galatians 2:17-19

i struggle with the line that seperates bitterness and concern. i have overwhelming concern for people, but when does it begin to consume me? i believe that paul, although very bold in his statements, kept a strong peace of mind. far too often, i mistake my restlessness for passion.
