At the end, Saul’s life is empty, miserable, and meaningless. It is lacking. What is missing?
Trust in God. He chooses to follow his own path over and over rather than follow God’s guidance. It was a trust issue. Saul was always looking for a solution rather than trying to find the Lord Himself.
Satisfaction in God. Saul was never content. Being God’s king was never enough. He was restless to get more wealth and monuments instead of destroying the Amalekites. He was not at peace with being God’s king in the moment, rather he tried to secure his future instead of being fulfilled in his current role as king.
Both of these missing pieces lead us to the ultimate conclusion, Saul did not know God. Regardless of his spiritual fervor, Saul’s lack of trust and satisfaction reveal a heart that is unaware of God’s gracious love and His strength and power.
