How to display health using GUIText?

I want to display my health as the GUIText and decreasing when the player hits. How to code based on my health script?

Here is my healthscript

using UnityEngine;
 using System.Collections;

 public class HealthScript : MonoBehaviour {

     public static HealthScript instance;
     public int hp = 1;
     private GUIText scoreReference;
     private GUIText highscoreReference;
     private static int _highscore = -1;
     public int highscore { 
         get { if (_highscore == -1) 
             _highscore = PlayerPrefs.GetInt("Highscore", 0);
             return _highscore; 
         }
         set {
             if (value > _highscore) {
                 _highscore = value;
                 highscoreReference.text = _highscore.ToString();
                 PlayerPrefs.SetInt("Highscore", _highscore);
             }
         }
     }

     public bool isEnemy = true;


     private static int points;
     public void Damage(int damageCount) {
         hp -= damageCount;

         if (hp <= 0)
         {
             // Dead!
             Destroy(gameObject);
             points++;
             scoreReference.text = points.ToString();
         }
     }

     public void gameEnd() {

         highscore = points;
         points = 0;
     }


     void Start()
     {
         scoreReference = GameObject.Find("Score").guiText;
         highscoreReference = GameObject.Find("HighScore").guiText;
         scoreReference.text = points.ToString(); 
         highscoreReference.text = highscore.ToString ();
         instance = this;
     }

UPDATE: I DON'T WANT TO DISPLAY ENEMY HEALTH, THIS SCRIPT WAS ATTACHED TO EVERY ENEMY

I recommend you to use OnGui method always to show the interface of the game

void OnGUI(){
    GUI.color = Color.red;
    GUI.Label(new Rect (20,20,200,20), "Health = " + hp);
}

All the documentation you need to understand this code is here:

GUI.Label http://docs.unity3d.com/ScriptReference/GUI.Label.html OnGui method: http://docs.unity3d.com/ScriptReference/MonoBehaviour.OnGUI.html

Hope this help you, ask if you have any troubles with this code!

You can use a variable to show on the GUI with C# easily by doing:

var myNiceVariable = "Showing the health values!";
var guiText = GameObject.Find("GUI Text").GetComponent(GUIText);
guiText.text = myNiceVariable;

Or you can use the OnGui method, you can add to your script:

void OnGui(){
     GUI.Label(new Rect (5,5,10,100), "Health: " + hp);
}

Code taken from here and here.
