It is The Lord who will enable us for Battle

As for God, his way is perfect; 
   the word of the LORD is flawless. 
   He is a shield 
   for all who take refuge in him.

For who is God besides the LORD ? 
   And who is the Rock except our God?

It is God who arms me with strength 
   and makes my way perfect.

He makes my feet like the feet of a deer; 
   he enables me to stand on the heights.

He trains my hands for battle; 
   my arms can bend a bow of bronze.

You give me your shield of victory, 
    and your right hand sustains me; 
    you stoop down to make me great.

Psalm 18:30-35 (NIV)
