“Kingdom of God” or “Kingdom of Heaven” can be found over 80 times in the New Testament. Every kingdom has a rule (authority), region (people to rule over), and a realm (land/territory). God gave mankind rule over the Earth but they rejected this responsibility with their sin. This sin handed authority to the kingdom of darkness. Jesus reestablished the Kingdom of God with His death and resurrection! He has given authority to believers to build the Kingdom in His Name!
