The Lord Said: "Yes, That's What I Said."

 I Samuel 23:1 Now they told David, “Behold, the Philistines are fighting against Keilah and are robbing the threshing floors.” 2 Therefore David inquired of the Lord, “Shall I go and attack these Philistines?” And the Lord said to David, “Go and attack the Philistines and save Keilah.” 3 But David's men said to him, “Behold, we are afraid here in Judah; how much more then if we go to Keilah against the armies of the Philistines?” 4 Then David inquired of the Lord again. And the Lord answered him, “Arise, go down to Keilah, for I will give the Philistines into your hand.” 5 And David and his men went to Keilah and fought with the Philistines and brought away their livestock and struck them with a great blow. So David saved the inhabitants of Keilah.

The Lord does not mind repeated questions.  David's leadership showed a marked difference from that of Saul. David asked God.  God answered.  But David also received conflicting advice, so he asked again. Rather than rebuking David for doubting Him, God repeated His answer with the assurance of victory. It was a less for David and his men. God indeed was able to deliver, and David was learning to listen to God. We need to be willing to ask God again and again. We also need to pay attention to those whom God answers and learn to listen like they do.
