Fear

Much of what we do in this life is motivated by fear: Fear of loss,
pain, lack, vulnerability, shame, etc. For example: We work because
we fear lack--being without things we need.

When people or circumstances threaten our security, wellbeing, or
comfort, it can feel like a battle line drawn up against us.

God did not promise what our victory would look like. He did promise
that the battle would be won, on His terms and in His way (which is
always best), as we trust Him and follow His instructions.
  

After the Arameans saw that they had been routed by Israel, they
  sent messengers and had Arameans brought from beyond the River, with
  Shophach the commander of Hadadezer's army leading them. When David
  was told of this, he gathered all Israel and crossed the Jordan; he
  advanced against them and formed his battle lines opposite them.
  David formed his lines to meet the Arameans in battle, and they
  fought against him. But they fled before Israel, and David killed
  seven thousand of their charioteers and forty thousand of their foot
  soldiers. He also killed Shophach the commander of their army.
