There is a revealing story in 1 Samuel 18, where Saul tries to lure David into a trap. The situation is somewhat complicated, in that Saul wants David to marry his older daughter Merab. She is offered to David as his wife, but with Saul there is another motive. He sees this as an opportunity to get rid of David by the hands of the Philistines. I love Davids response, "who am I, and what is my life or my father's family in Israel, that I should be son-in-law to the King?" Davids response was one of total humility, showing that in his own mind he really wasn't worthy of the Kings daughter in marriage.
This first marriage didn't work out, but there was a younger daughter, Michal, "...who loved David." So once again Saul begins to weave his deceitful web to try and get rid of David. During this entire story, David has one thing in mind, and that is to be nothing but a faithful servant to his king. Saul has his servants communicate to David his desire for David to be his son-in-law. Once again David's response is one of caring and great concern with total humility, "Does it seem to you a light thing to be a king's son-in-law, seeing I am a poor and lightly esteemed man?" What happens next is the subtile trap of Saul, "Then Saul said, “Thus you shall say to David: ‘The king does not desire any dowry but one hundred foreskins of the Philistines, to take vengeance on the king’s enemies.’ ” But Saul thought to make David fall by the hand of the Philistines.” (1 Samuel 18:25 NKJV)
It is here that we see the deceitfulness of Saul, and his attempt to destroy David in any way possible. Sometimes in our attempt to serve others, and to minister with as much humility as we are capable of, still is not enough to change the heart and mind of someone who dislikes us or sees us as some kind of threat. What is most amazing is the willingness of David to be obedient to the wishes of his king. It says that, "...David arose and went, no hesitation on David's part, total submission to the will of his king. The one thing that truly reveals the wickedness and deceitfulness in Saul's heart is found in, “Thus Saul saw and knew that the Lord was with David, and that Michal, Saul’s daughter, loved him; 29 and Saul was still more afraid of David. So Saul became David’s enemy continually.” (1 Samuel 18:28–29 NKJV)
Even when the Lord is with us, we can't please everyone. But, we can always desire to be well pleasing to the Lord. Even Saul recognized that the Lord's hand was on David. “And whatever we ask we receive from Him, because we keep His commandments and do those things that are pleasing in His sight.” (1 John 3:22 NKJV)
