Pray to the Load to do mighty works from us

I Samuel 19:18-24
David was became enemy of Saul, he was not an companion.
David went to Samuel at Ramah, then they went to Naioth and stayed there.
Saul sent men to capture him three time, but all of them went to there saw a group of prophets prophesying, with Samuel standing there as their leader, the Spirit of God came upon Saul's men they also prophesied.
Finally Saul went there, the Spirit of God came even upon him, and he also prophesied in Samuel's present. He lay that way all that day and night. Then David have time to escape from Naioth.
Why?
Enemy of God's men when Spirit of God come upon them it is possible prophesying.
When heart and mind changed for confronted with personal profit , a friend or companion become enemy. There are not love within them.
Prophesying is the work of Spirit of God, it's power no only is Saul's evil plan frustrated, but the king himself becomes 'infected'. Like his messengers- turn prophet.
Samuel was a leader in prophet school. Spirit of God help David left there from Saul.
How?
the Spirit has mighty power to do everything, even change mind of men. I need to pray to the Load, let Holy Spirit come upon me, and let me could be a servant- preaching Gospel and honor the name of the Load.
