You're making a dogmatic statement--not really asking or discussing. I would partly agree with you. When Jesus came he in a sense brought the Kingdom of Heaven with him--not in the eschatological sense, but in the sense of his power and authority, which necessarily rests with him.
But I don't think he was saying anything other than the Kingdom had drawn near, and was in the midst of Israel through his person. It was not accessible in the eschatological sense, which would come, as he said, at the end of the age.
The Kingdom Jesus brought with him endowed the Church with power to testify to him and to his presence with us. He enables us to live in his righteousness and to proclaim his coming Kingdom with power and authority, enabling people to be loosed permanently from the guilt of their sins, and to find in heaven a permanent place for their souls.
