The easiest way to understand the Kingdom of God is to focus on the King. Jesus Christ is the KING of Kings and LORD of Lords. God reigns supreme over any being in heaven or on earth. Is there anywhere in God’s universe that is not part of God’s Kingdom? No. Is there anywhere in the middle of God’s universe where there are outposts of rebellion? Yes. There are demonic realms, communities and nations where they are in rebellion against God. There are people on this earth who reject God’s authority and refuse to live in obedience to the King.
In the Lord’s Prayer, Jesus taught us to pray that the citizens of His Kingdom would obey Him, the same way that the angels in heaven obey Him. When we obey Jesus Christ, we testify that Jesus’ way is the right way (Righteousness). We testify that what God says is true. When we live according to God’s teachings, we show that we are citizens of God’s Kingdom.
Jesus Christ was specific in teaching us how to conducting our personal, family and governmental activities according to His Word. When a group of Christians live according to God’s Word and influence the community or nation to live according to God’s Word, they bring that community or nation into a right relationship with God’s Kingdom.
The rebellion of darkness is at war with God’s Kingdom of righteousness. Those who reject God’s righteousness live according to worldly pleasures, the teachings of demons, and their own desires. They are part of the rebellion of darkness.
The Lord’s Prayer
9 In this manner, therefore, pray:
Our Father in heaven,
Hallowed be Your name.
10 Your kingdom come.
Your will be done
On earth as it is in heaven. (Matthew 6:9-10)
We are to focus more God’s Kingdom and God’s right way of living than on what we wear and what we eat.
33 But seek first the kingdom of God and His righteousness, and all these things shall be added to you. 34 Therefore do not worry about tomorrow, for tomorrow will worry about its own things. Sufficient for the day is its own trouble. (Matthew 6:33-34)
