Using the wisdom from the gift to make right decision

I Samuel 27:1-12
David though to himself, the best way he can do is to escape to the land of Philistines, then Saul will give up searching for him anywhere in Israel.
David and the six hundred men with him left and went over to Achish son of Moath king of Gath.
David said to Achish,"If I have found favor in you eyes, let a place be assigned to me in one of the country towns, that I may live there. Why should your servant live in the royal with you?"
So Achish gave David Ziklag, and it has belonged to the kings of Judah ever since. He lived there one year and four months.
David and his men went up and raided the Geshhurites, the Girzites and the Amalekites, he did not leave  a man or woman alive, but took sheep and cattle, donkeys and camels and clothes. Then he returned to Achish. David told him he fight against the Negev of Judah. Achish trusted David and said to himself " David has become so odious to his people, he will be his servant forever."
Actually, David attacked the enemy of the Judah was living in south of Judah. David left no one to tell the tale.
Why?
This is the second times David escaped to living among Philistines. Achish was fool also to trust David.
David make decision this time by himself.
David cheated Achish again let Achish believed he will not go back to Judah anymore.
Last time David went to Gath alone, this time six hundred men went with him and his wives. David had force with him, so he can do more things and be more honor before the men.
It is the wisdom from the Load gave to David. Somehow David should ask the Load should he may went to Gath before make this decision.
How?
If we obey the decrees of the Load, God bless our life. Even the decision we made is under the allowance of the Load. The Load give us the wisdom to make decision in our life. The main principle is follow the commands of the Load to love the Load and love people. Doing righteous and compassion to others.
