A warhorse was bred for power, a sound mind, and to fight the normal flight instinct. A sound mind being paramount. Job 39:19-25 talks of a war horse. These horses would literally quiver with anticipation before a battle would begin. I drew this with our Christian walk in mind. God gave the warhorse his power. We trust not in the strength of the horse, but in the strength of the one who gave it to the horse. We do not glory in our own strength, but in the power and strength of God. Thus we can approach a battle with Anticipation knowing God will work all for our benefit.
