The fact that you can ask if God will still control us when we get to heaven tells me that you still do not fully grasp the basis for God’s sovereignty and that your thinking is still man-centered.
God is sovereign not because of who you are or where you are, but because of who he is and what he is. He controls all things because this is what it means to be God. His sovereignty is first an ontological and metaphysical issue and not a soteriological issue. It has nothing to do with where we are or our state and condition. We will never become autonomous and independent from God. His sovereignty is not a game, where we will arbitrarily decide to go by one set of rules for a while, and then when we have stopped playing we will go by another set of rules. He controls all things because he is God.
Be careful when you ask a question like this so that you do not blaspheme, because your question amounts to “Will God still be God when I am in heaven, or will I have independence from God and become equal to Jehovah himself in his freedom?” Nevertheless, I do not wholly blame you, because Calvinists and Reformed theologians have trained people to think from a narrow soteriological viewpoint even when the question pertains to a broad ontological and metaphysical issue. If you ask them a metaphysical question, they will give you a soteriological answer. This has resulted in much absurdity, and sometimes blasphemy. For an example, see my article, “But What About the Thingamajig?” As for you, always think of God with the utmost fear and reverence. Do not blaspheme, not even indirectly or by implication.
