Are you trained by God to fight? How were you trained? Psalm 143-145

Psalms 144:1-2
​ Blessed be the Lord, my rock,
Who trains my hands for war,
And my fingers for battle;
My lovingkindness and my fortress,
My stronghold and my deliverer,
My shield and He in whom I take refuge,
Who subdues my people under me.

The implication of the above verses is that you and I, as God's children, will, at some point and time in our lives, be in war and engaged in battle.   There would be no reason for David to tell us that God "trains" our hands for war and than not have us in a war.   God is constantly giving us training on how to be victorious in our walk with Him.   He trains us for a purpose.  That purpose is to stand for Him and to reflect Him in all that we do.   His training, like David's, is often in the wilderness, tending sheep and protecting them from lions and bears.   David learned to fight the giant by first fighting the bears and lions who would attack the sheep in his charge.  Being a shepherd was typically a boring job.  Sheep are dump and you simply have to rescue them from themselves most of the time.  So, we can imagine David practicing with his sling daily, just to break the boredom.   Yet, God will allow a lion or bear to come along just to get David's heart going and to see if all that practice with his sling would pay off.   Little did David know that one day he would actually take a man's life with that little sling.   So, too, with us.   We practice our day to day lives, fighting the little battles He has for us, only to realize that some day we will have greater battles to fight.   Notice in the second verse of the above lines of "how" God teaches David, or, perhaps, better, "what" He teaches David.   David tells us that what he learned was that it isn't really his fight at all.   This is, in reality, God's fight.  God is the fortress, not David's skill.   God is the stronghold, not David's might.   God is the shield, not David's talents.   God subdues the people, not David's charm and leadership prowess.   David was trained to battle and fight and what He learns is that it is not his skills that matter, but God's character.
