Urban Bridge Church brings heaven to earth?

Thus saith Urban Bridge Church:

We believe that it is our responsibility and privilege to bring heaven to earth.

A dissenting view from Malcolm Muggeridge:

To proclaim a kingdom of heaven on earth, on the other hand, is both deceptive and intrinsically absurd. The maintenance of such a notion requires mental gymnastics so extreme and so strenuous that they usually produce dementia.
