Who am I?

I'm the man that stands ready in the night to do violence on your behalf! That's sees the dark side so your eyes never witness it! That runs to the sound of the gunfire so you can run away! The man that will sacrifice his life even though you might hate me! I'm your eyes in the middle of the night so your children can sleep safely! People don't call me to tell me about their joyful day! They call because their husband is drunk and punched her in the face! Their child ran away! Their daughter was abused by the neighbor! I help you gladly because I took an oath! I believe in that oath! Whatever you may think of me or my uniform I will be there if you need me! Just remember I have problems just like you! I feel pain just like you! I get my strength from God, my hope from Jesus, and am guided by the Holy Spirit!
