There is a dimension of God called the Lord of Host. The commander of the armies of heaven. David showed up in the battle field armed but He knew the battle had an owner did you know that it is not the stone that David threw that brought the giant down? Remember the giant fell face forward out of the laws of gravity when you are hit from the front you fall face backwards meaning the rock of ages was in charge of the battle. What hit Goliath came from behind hence he fell face forward.
May battles be settled from the chambers of zion. May you enter your rest.

Psalm 46:9-10 (NIV)

9 He makes wars cease
to the ends of the earth.
He breaks the bow and shatters the spear;
he burns the shields[a] with fire.
10 He says, “Be still, and know that I am God;
I will be exalted among the nations,
I will be exalted in the earth.”
