Read 1 Samuel 17:48-51
All David had was a sling and a stone as he took on a giant wearing 200 pounds of armour. It may seem silly, but that's the way God operates. In the final analysis, there was a whoosh, whoosh, whoosh—one stone flew through the air, and that's all there was to it. Goliath fell like a sack full of sand. Got any more giants?
I don't know what your intimidating giant is today. It may relate to your job, your roommate, or your school. Maybe it is a person, a lawsuit, unemployment, a disaster...maybe even your own partner in life. Perhaps it is some fear that is lurking around the corner, sucking your energy and draining your faith. God is saying to you right now, "All I ask of you is five smooth stones and a sling of faith. I'll take it from there. You don't have to wear somebody else's armour. You just trust Me. And I'll strip you down to nothing but faith, and then I'll accomplish a victory where I'll get the glory. But as for you...you trust Me."
Perhaps you don't know what lies across the valley. Maybe you can't get a handle on what that giant is; but it's there, haunting you. That uncertainty alone is a giant. But look at that worry in comparison to the Lord God Himself, and say, by faith, "The battle is Yours, Lord. It is Your battle. I lean on You. I give You all my weapons, all my skills, and I stand before You, trusting You."
It is God's love for us that causes Him to bring us to an end of our own strength. He sees our need to trust Him, and His love is so great that He will not let us live another day without surrendering our arms to Him, giving Him our fears, our worries, even our confusion, so that nothing becomes more significant to us than our Father.
Never, ever forget it: the battle is the Lord's!
