Paradox #1
The moral conflict in 1 Samuel 16:15 could be seen in the way it portrays God sending an evil spirit to trouble Saul. This can create inconsistency with the view that God is wholly good and not responsible for causing harm or distress. It may seem contradictory to some that a benevolent and loving God would allow or cause suffering in this manner.
