But David found strength in the Lord his God

1 Samuel 30:1-10

David and his men reached Ziklag on the third day. Now the Amalekites had raided the Negev and Ziklag. They had attacked Ziklag and burned it, and had taken captive the women and everyone else in it, both young and old. They killed none of them, but carried them off as they went on their way.

David was greatly distressed because the men were talking of stoning him; each one was bitter in spirit because of his sons and daughters. But David found strength in the Lord his God.

Then David said to Abiathar the priest, the son of Ahimelek, “Bring me the ephod.” Abiathar brought it to him, and David inquired of the Lord, “Shall I pursue this raiding party? Will I overtake them?”

“Pursue them,” he answered. “You will certainly overtake them and succeed in the rescue.”

David and the six hundred men with him came to the Besor Valley, where some stayed behind. Two hundred of them were too exhausted to cross the valley, but David and the other four hundred continued the pursuit.

Why?

David was very distressed, his action was asked the Lord.

It is another chance let David to kill the people of Amalekites, and they take captive the women and everyone else in Ziklag.

The sadness, frustration, and anger focused on David, because David is their leader, and David needs to bear this responsibility.

David knew he belonged to the Lord so the first thing he did was ask the Lord to pursue their enemies. It is not to make the decision in a revenge mood.

How? 

No matter what happens to me before making the decision, I should ask the Lord. Don't make decisions in a hurry situation or angry mode.
