Making a god of sovereignty results in weak theology. God is sovereign, but it is only one aspect of his character. Sovereignty is not a concept representing philosophical perfection. It must mean something in terms of the character and activities of God.
God is constrained by his character. He is constrained by his choices about how he will operate that flow out of his character. If God is sovereign, he can choose to constrain his activity. That does not limit his freedom or omnipotence.
Once God created a finite world and finite people to live within it, and committed himself to working with them, he constrained himself to working within time. He is beyond time, so he can still move across time, but if he intervened on earth outside the order of time, his interventions would not make sense to those living within time. God has a strategy for restoring the earth. This involves a sequence of interventions on earth that makes sense in terms of finite time.
When God created people and spirits and gave them real freedom, he constrained himself. He could have kept them under his control, but he decided against that, because the wanted them to be free to do things that are contrary to his will. Having made that choice, it was almost inevitable that spirits or people would do things that are contrary to his will. This allows them to constrain his ability to accomplish in purpose in various ways. Every time I resist his will, I hold back his plans.
I wonder how many people the Holy Spirit spoke to before Abraham heeded the call to move to the land he was called. I presume he had spoken to many people, but was ignored. I presume some heard, but chose to disobey. Abraham was the first to hear and obey, so he received the promise of blessing.
Some will say that God knew in advance, the people who refused the call would refuse. That is playing games. Does it mean that he was not calling those people seriously, but just speaking to prove that they were rebellious? That would be insincere. If God’s will is limited to what actually happens, it becomes a bit meaningless.
