Staying on the theme of king Saul . . .
1 Samuel 19:20-24 NKJV - "Then Saul sent messengers to take David. And when they saw the group of prophets prophesying, and Samuel standing as leader over them, the Spirit of God came upon the messengers of Saul, and they also prophesied. And when Saul was told, he sent other messengers, and they prophesied likewise. Then Saul sent messengers again the third time, and they prophesied also. Then he also went to Ramah, and came to the great well that is at Sechu. So he asked, and said, "Where are Samuel and David?" And someone said, "Indeed they are at Naioth in Ramah." So he went there to Naioth in Ramah. Then the Spirit of God was upon him also, and he went on and prophesied until he came to Naioth in Ramah. And he also stripped off his clothes and prophesied before Samuel in like manner, and lay down naked all that day and all that night. Therefore they say, "Is Saul also among the prophets?"
How do we avoid this idea of Mind Control when we see king Saul flipping back and forth from first having a good Spirit of God, only to be stripped and subsequently being given an evil Spirit. If a person didn't know any better, they might think of king Saul as a pre-image of young Saul as found in early Acts. However, regarding king Saul, we soon find that God does indeed strip Saul of a Good Spirit only to give him an evil Spirit that clearly leads him into sin. We then find that Saul gives David a reprieve because he, Saul, doesn't seem to be caused to commit evil. Incredibly, king Saul then again is consumed by the Evil Spirit from the Lord, who causes Saul to attempt to murder David yet again. Saul then summons others to murder David, but here, we see that a good Spirit from the Lord is upon him, and now he is behaving completely differently.
Back and forth . . . the Lord causes king Saul to think and behave as he does. Saul is perhaps the single most inconsistent human in the Bible, but is this his fault? Is this his choice? Did king Saul choose to act the way he did, or were the contents of his life chosen for him . . . including his kingship? That's right . . . Saul's life was laid out before him, and there was nothing he could do about it.
If anyone had the right to complain about a lack of free will, it would certainly be king Saul.
