“David said unto Saul, I cannot go with these; for I have not proved them.” 1 Samuel "17":39
There is no spiritual value conferred by office. Wearing the king’s armor does not give a man kingly qualities. It is striking to remember that David already knew himself to be the anointed king of Israel. What more natural, then, than to put on the king’s apparel, especially as he was fighting the king’s battles?<br/><br/>He did try the armor, but he soon took it off again. Inwardly, he must have realized that spiritual power does not come from earthly accompaniments but from a heart relationship with God. David had entered into such a relationship by secret experiences in daily life. These hidden victories with God provided him with a sufficient weapon for his public conflict. He was much better off without the well-intentioned but artificial aids offered by Saul.
