Meant for More??

I have the word of God on my mind, Into my heart it's enshrined, born and raised this way, but I live on my own time. This life is mine to live, but I give it all to Him, He's given all for me, and I'm just a worthless kid. I wasn't supposed to live, but he spared my life! a pre-mature little soul, and yet I wonder why. Why would he spare my life? was I meant for more than this? will I just sit and wonder, or will I make the most of it?
