Cannons

Phil Wickham's song Cannons makes me think alot
The chorus goes
"You are holy
Great and mighty
The moon and the stars
Declare who you are
I'm so unworthy
But still you love me
Forever my heart
Will sing of how great You are"

To me it is so straight forward. Saying I'm so unworthy but still you love me.
God loved us so much that he gave his only son. Since god has done that for us, can't we do the simplest thing such as praising him through the day, or even mentioning him to a friend at school. I wonder to myself sometimes why I don't take that leap, and just talk to my friends.
It's my senior year, so what impact am I leaving behind to people?
God has done so much for me, but quite frankly I feel I haven't done half as much for him.

1 John 4:20
If anyone says, "I love God," yet hates his brother, he is a liar. For anyone who does not love his brother, whom he has seen, cannot love God, whom he has not seen.
