1 Chronicles 12:1 "These were the men who came to David at Ziklag, while he was banished from the presence of Saul son of Kish they were among the warriors who helped him in battle."
2 Timothy 2:4 "No one serving as a soldier gets entangled in civilian affairs, but rather tries to please his commanding officer."

When David was a fugitive from Saul, the men who followed him recognized his rightful place as King of Israel and they developed a deep loyalty to him.  These men were transformed from distress, debt, and discontentment (1 Samuel22:1-2) into becoming mighty men of war. Having joined David, they quickly realized that they were joining a conflict.
New believers may not immediately realize that they have recently entered the greatest war of all-time - the war between good and evil! Claiming the faith of Yeshua (Jesus), they are instantaneously thrust into a battle with an enemy who seeks to rob, kill and destroy them. [John 10:10] So, even with the powerful protection of a loving Father, they may find themselves dodging bullets, or even taking hits from the enemy, as they wake up to the unavoidable reality of spiritual warfare; and this time can be discouraging, even to the point of wanting to give up the faith, especially if they weren't warned or prepared at all for the conflict…
When we choose to follow Jesus we should realize we have been enlisted into a spiritual army, of which He is the General.  And as we mature, taking more responsibility, we realize the danger and wastefulness of becoming entangled with the affairs of this life.  This can take time, but little by little, with plenty of practice, we become equipped and experienced with the spiritual weapons that are necessary for real victory against the enemy of our souls!
Wake up to the warfare, stay in training, fight the good fight; the joy of spiritual victory is so worth every effort!
