The camera zooms in on David kneeling by a stream.  You are taken by how young he looks.  The only soundtrack is the water moving fast over the river rocks.  David is focused on choosing five perfect stones.  Looking closer, you see that his lips are moving.  Zooming in, you make out his words:

“The LORD is my shepherd, I shall not be in want.  He makes me to lie down in green pastures, he leads me beside quiet waters.  He guides me in paths of righteousness for his name’s sake.”

David’s focus now shifts from the stones to the sky.  With bright eyes and confidence, he looks with just as much focus to the heavens.  He speaks louder and the camera slowly pans out from above. . .

“Even though I walk through the valley of the shadow of death, I will fear no evil, for you are with me, your rod and your staff they comfort me.”

The wide view now enables you to see that David is in a valley and on either side are ranks of men prepared for battle.  The music picks up intensity.  David’s position betrays his confidence.  He looks so vulnerable and small between those two armies.  He raises his voice further:

“You prepare a table before me in the presence of my enemies.  You anoint my head with oil; my cup overflows.”

The giant paces back and forth.  Goliath is fierce.  He breathes violence and hurls insults at both David and David’s God.  There is another giant on the other side of David.  It’s not King Saul, although he did stand head and shoulders above most men.  It is FEAR.

God has lifted His favor from Israel’s king because of his rebellious heart.  The void is felt through the ranks of his men, and they are terrified in Goliath’s presence.

David stands now.  He is flanked by violence and terror.  He begins to run toward Goliath and sings in full voice:

“Surely goodness and love with follow me all the days of my life, and I will dwell in the house of the LORD forever.”

With the swing of a sling and the slash of a sword, two giants were defeated that day.
