The Kingdom of Heaven - the Kingdom of Christ. It is not a worldly kingdom. The earthly kingdoms wherever they are and however nice they are, do not come close to the Kingdom of Heaven. Dwelling of the Holy Spirit in us is the Kingdom of Heaven. Don't be miserable, Heavenly Kingdom is from God onto Whom we put our hope. We as Christians are hoping for the Day of Redemption, when God takes us and we will dwell with Him forever. Remember the word of our holy apostle and church planter Paul: Philippians 1:21 "For to me, to live is Christ and to die is gain"
