This song tells the story of David and Goliath:

“Now there must have been some laughter among the Philistines/At the sight of this scrawny little shepherd/Coming out to meet the record-breaking mammoth of a man who was a killing machine/But it didn’t shake David ’cause he was smart enough to know/It’s more the size of who you put your faith in than the size of your foe”

I don’t know what you are going through today, this week or this year, but rest assured that God is bigger than whatever you are facing.  God is big enough to take care of you.  When you put your faith in Him, you are putting your faith in Someone bigger than anything you could face.  He will take care of you.
