The Lord's Prayer "your kingdom come"

What is God's kingdom and how should we understand it? When we think of a kingdom we tend to think about a geographical domain that in under control of a leader or country. Or a realm of control. The United States of America has clearly defined borders where you can look on a map and say there it is or isn't. This isn't how the kingdom is used in the New Testament. When Jesus and the apostles use the word kingdom they mean something else. The kingdom is the right to rule and not real estate. When Jesus prayed for God's Kingdom to come he was asking that God would exercise His authority, His right to rule based on His might, power and glory. When we pray this prayer we are asking God to bring abut His right to rule on this earth. We want God to display His kingly rule and power over all of creation. We are asking Him to destroy the kingdom of darkness. We seek that He would be ruler over all. One day He will rule over all the realms of this earth. We pray that His rule would expand until the day comes when He takes the entire realm. Is His rule expanding over your life? Pray that He would rule in all your affairs this week.
