Which Part Is Mine

One of my favorite songs has always been "Which Part is Mine" by Michael McLean. In the song a mother asks the Lord "Which part is mine?". I have wondered that so many times in my life.  How much am I expected to do myself and at what point have I done my best? I have found the best way to get an answer to this question is through prayer. I can't do everything that's why I have a Savior to step in where I can't do it all. The song ends with the mother receiving an answer to her prayers. She can feel the spirit telling her that Heavenly Father has heard her prayers. The song says "After I've done my best, I know you'll do the rest".  When it all comes down to it the prayer and inspiration from the Lord are the best way to know when we've done enough.  We do our best then he'll do the rest!!
