Don't try to help God to do something

I Samuel 26:1-25
The pro-Saul Ziphites second times lay information against David, Saul to chase David on the hill of Hakilah.
David and Abishai went to the camp of Saul, all of them were lying asleep inside the camp. No one saw or know about it, nor did anyone wake up, because the Load had put them into a deep sleep.
David and Abishai may kill Saul in that moment, but David didn't, he said "As surely as the Load lives, the Load himself will strike him; either him time will come and he will die, or he will go into battle and perish. The Load forbid him lay a hand on God's anointed. They got the spear and water jug that are near his head.
Then David crossed over to the other side and stood on top of the hill some distance away; talked to Saul and Abner. David said "Why is my load pursuing his servant? What have I done,and what wrong am I guilt of? If the Load has incited you against me, then may he accept an offering. If men have done it, may they be cursed before the Load! They have now driven me from my share in the Load's inheritance and have said,'Go, serve other gods'. Do not let my blood fall to the ground far from the presence of the Load."
Saul confessed have acted like a fool and have erred greatly, and blessed David ; you will do great things and surely triumph.
Why?
David loved the Load more than himself, he loved God with action- respect God's anointed.
David knew that God did not need his help to put him on the throne.
David entered to the camp of Saul for the Load is with him.
David can do great thing for he do the right things and righteous.
How?
Don't try to do thing to help the Load, for the Load want us do what we have to do. Obey his commands and honor the name of the Load. Do my responsibility to be an honest servant and pray to the Load.
