Governance and authority of God is not in a Theocratic system, it is in communion. God holds all things in being. In him all things live, move, and have their being. Concerning the authority of Christ, we must reflect deeply on the verses:
"in him were created
all things in heaven and on earth:
everything visible and everything invisible,
Thrones, Dominations, Sovereignties, Powers –
all things were created through him and for him.
Before anything was created, he existed,
and he holds all things in unity."
An 'emperor/kingly Christ' is too less to explain it.
As communion is the way of God's governance, the body of Christ must have the life style of communion as the self-authority working within the body. Whole creation is part of the body, the church where Christ is the fullness. The models of authority shaped towards communion may help us to experience a new pathway to experience the reality of 'in him we (together) live, move, and have our being.
Our desire/ prayer that 'your will be done' may be the best way to acknowledge the authority over our life. If that is sincere, we will be seeking the mind of Christ in our words and deeds. It will lead us to stand for peace and reconciliation. Peace is not simply relaxation, free of tension, and calm and cool. Peace is the fruit of manifold ways of desiring and working for life to be filled in everyone and everywhere. That is the will of the Father.
