Protection is your calling as a Man of God. Don't let anyone tell you differently.
Although we are to show love no matter what we do, even in violence, we are not called to be pacifist. I have been working in Haiti, where the threat level toward American missionaries is extremely high. I always find myself magically reading about David during these missions.
1 Samuel 26 So Saul took 3,000 of Israel’s elite troops and went to hunt him down in the wilderness of Ziph. Saul camped along the road beside the hill of Hakilah, near Jeshimon, where David was hiding. When David learned that Saul had come after him into the wilderness, he sent out spies to verify the report of Saul’s arrival.
David slipped over to Saul’s camp one night to look around. Saul and Abner son of Ner, the commander of his army, were sleeping inside a ring formed by the slumbering warriors. “Who will volunteer to go in there with me?” David asked Ahimelech the Hittite and Abishai son of Zeruiah, Joab’s brother. “I’ll go with you,” Abishai replied.
So David and Abishai went right into Saul’s camp and found him asleep, with his spear stuck in the ground beside his head. Abner and the soldiers were lying asleep around him. “God has surely handed your enemy over to you this time!” Abishai whispered to David. “Let me pin him to the ground with one thrust of the spear; I won’t need to strike twice!” “No!” David said. “Don’t kill him. For who can remain innocent after attacking the Lord’s anointed one? Surely the Lord will strike Saul down someday, or he will die of old age or in battle. The Lord forbid that I should kill the one he has anointed! But take his spear and that jug of water beside his head, and then let’s get out of here!”
So David took the spear and jug of water that were near Saul’s head. Then he and Abishai got away without anyone seeing them or even waking up, because the Lord had put Saul’s men into a deep sleep. David climbed the hill opposite the camp until he was at a safe distance. Then he shouted down to the soldiers and to Abner son of Ner, “Wake up, Abner!” “Who is it?” Abner demanded.
“Well, Abner, you’re a great man, aren’t you?” David taunted. “Where in all Israel is there anyone as mighty? So why haven’t you guarded your master the king when someone came to kill him? This isn’t good at all! I swear by the Lord that you and your men deserve to die, because you failed to protect your master, the Lord’s anointed! Look around! Where are the king’s spear and the jug of water that were beside his head?”
We are surrounded by God's anointed on a daily basis. Our friends, family, colleagues.....we are called to be used by God, through our natural talents and abilities, to protect his anointed. Do not fear that calling. God expects you to use the size and strength he gave you to protect the weak and helpless. You were made in his image. You were given strength for a reason. Do not let the world minimize the importance of your role as a protector.
