Who? Me? The Worst of Sinners?

Paul regarded himself as the "poster child" for sinners-who-need-Jesus. This is something I find incredibly difficult to emulate. And yet it is the only way that I will truly be able to love the other sinners in my area of influence. How can I truly love and serve other sinners unless I am consciously aware of how undeserving I am of the love and service Jesus has shown me?
