What do you consider to be your "greatest work"? Your children?, job?, marriage? last nights dinner? How big is your vision for what your greatest work will be?
In the movie "Charlotte's Web", Charlotte (the spider) tells Wilbur (the pig) that she's been working on her Magnum Opus, her greatest work. Her children. In Psalm 139 David tells us that we are "amazingly and miraculously made". Know this...even if you don't know what your greatest work is...know that you're God's. We are His Magnum Opus and He has created us for His good pleasure. (Eph 2:10 For we are his masterpiece, created in Christ Jesus for good works that God prepared long ago to be our way of life.)
