Lesson to learn from the story of king David and king Saul

King Saul and king David was favoured and chosen of thy lord through prophet Samuel to lead the people

  But there behavior and obedience to the people and the lord differentiate them
      Obedience and forgiveness
ISamuel9vs15 king Saul disobey the law of the lord by offering sacrifice by himself which is duty of prophet Samuel, Samuel makes him realise but he does not think there's need for forgiveness
  David sin unto thy lord by sleeping with his servant wife (IIsamuel11vs3-4) and when he was called to order (IIsamuel12vs13)He realise his wrong doing and ask for forgiveness
        Oppression
Saul oppress the people of Israel (Isamuel14vs24)And the men of Israel were distressed, for Saul had adjured the people, saying,cursed be the man that eat any food until evening,that I may avenged on my enemies so none of the people tasted food. He add to there burden after going to war,his asking for fasting while they are dying
   IIsamuel23vs16-17 Be it far from me,O lord that I should do this the blood of the men that went jeopardy of their lives?therefore he would not drink. David reject the water which was been fetched for him because its was of too much risk and thinks he doesn't worth that sacrifice

    Do not touch nor curse anointing men of                          God
 David have the chance to kill his enemy,the king but he said Isamuel24vs6 And he said unto his men,the lord forbid that I should do this thing unto my master,the lord's anointed to stretch forth mine hand against him,seeing he is the anointing of God(David fear thy lord)
 When Saul is angry he doesn't have respect nor regard for men Of God (Isamuel22v17)And the king said unto the footmen that stood about him,turn,and slay the priest of the lord,because they knew when he fled,and did not shew it to me .But the servants of the king would not put forth their hand upon the priests of the lord. But Saul insists and called on Doeg the Edomite and he killed the priest(The servant fear thy lord but the Edomite,unbeliever will doesn't care)
          Spirit of David
 David always rejoice in the work of thy lord and praising him Isamuel8vs1-3 O lord our lord,how excellent is thy name in all the earth!who hast set the glory above the heavens,out of the mouth of babes and sucklings hast thou ordained strength because of thine enemies, that thou mightest still the enemy and the avenger. Whenever I consider thy heavens, the work of thy fingers, the moon and the stars,which thou hast ordained
   But Saul find it difficult to appreciate it goodness
  Note:We are all favoured in the sight of the lord. Our responsibility is to obey is LAW and appreciate is LOVE
