Heavenly Kingdom exists in two aspects, namely present and eternity. It is relatively easy to explain how Heavenly Kingdom comes when Jesus Christ comes to the world again to judge us, as stated in the Book of Revelation. The Heavenly Kingdom is also in us, as stated in Ephesians 2:6, "So that we came back from death with him, and are seated with him in the heavens, in Christ Jesus." It should be noted that "are" appears before "seated", meaning present time. However, for Christians, this Heavenly Kingdom at this moment is just "already but not yet". We've got the citizenship of this Heavenly Kingdom, but we must wait until it actually comes. We're just its citizens who abode in another country until we return to our "homeland", but we're still under its protection to a certain extent. It is similar to a Chinese who can seek help in another country via our Chinese Embassy.
In short, Heavenly Kingdom is already inside all Christians as our status. No extra experience is needed for getting close to it.
