Open Theism

Psalms 47:1-9 ESV
(1) To the choirmaster. A Psalm of the Sons of Korah. Clap your hands, all peoples! Shout to God with loud songs of joy!
(2) For the LORD, the Most High, is to be feared, a great king over all the earth.
(3) He subdued peoples under us, and nations under our feet.
(4) He chose our heritage for us, the pride of Jacob whom he loves. Selah.
(5) God has gone up with a shout, the LORD with the sound of a trumpet.
(6) Sing praises to God, sing praises! Sing praises to our King, sing praises!
(7) For God is the King of all the earth; sing praises with a psalm!
(8) God reigns over the nations; God sits on his holy throne.
(9) The princes of the peoples gather as the people of the God of Abraham. For the shields of the earth belong to God; he is highly exalted!

How can anyone subscribe to open theism unless this Psalm doesn't exist in their Bibles? Maybe I just don't understand open theism well enough, but to me it sounds like we are trying to put man on the throne. I don't want to be on the throne. God will do a better job.
