"This day the Lord will deliver you into my hand, and I will strike you and take your head from you." - 1 Sam 17:46
But there was no sword in the hand of David. - 1 Sam 17:50
That's worth reading again. And again. And again until it really sinks in, that a kid with a slingshot walks up to a giant and shouts at him: "I'm gonna cut your head off!" and he didn't have a sword in his hand.
What do you call that?
If that's what it really is, do you have it?
What Goliath is God calling you to face? And what sword are you waiting to acquire before you face him?
Is there something God has put in your heart, but you're waiting for the resources to accomplish it? You have to look at that giant and shout like David, "This day the Lord will deliver you into my hand, and I will... " Then run to that giant, and you'll find the sword you have been looking for is right there on his belt. God put it there for you. Go get it.
