You are wrong OP.
"As men grew to understand the Divinity of Christ they grew to see that the kingdom of God was also that of Christ it was here that the faith of the good thief excelled: "Lord, remember me when thou shalt come into thy kingdom."
So, too, as men realized that this kingdom stood for a certain tone of mind, and saw that this peculiar spirit was enshrined in the Church, they began to speak of the Church as "the kingdom of God".
[cf. Colossians 1:13; 1 Thessalonians 2:12; Apocalypse 1:6-9 and 5:10, etc.]
The kingdom was regarded as Christ's and He presents it to the Father
[cf. 1 Corinthians 15:23-28; 2 Timothy 4:1.]
The kingdom of God means, then, the ruling of God in our hearts; it means those principles which separate us off from the kingdom of the world and the devil; it means the benign sway of grace; it means the Church as that Divine institution whereby we may make sure of attaining the spirit of Christ and so win that ultimate kingdom of God Where He reigns without end in "the holy city, the New Jerusalem, coming down out of heaven from God.
