Open Theology is not supported in the Bible.
God does not have plan A, plan B, plan C.
God is not sitting in heaven with His fingers crossed hoping His creation will pick what He wants.
The bible teaches throughout that God declared before the foundation of the earth and brings about His plans because He is good.
Is a God that is fickle, manipulated by His creations, and not in control of every random molecule worthy of worship and praise?
