When we talk about the Kingdom of God reigning on the earth, many think of it as a farfetched idea made up by some theological imagination.
Be sure that the Kingdom of God will reign on the earth! God will reign over the earth through those He has called and they've harkened to His call and yielded to living His life with His help.
For in this way there will be richly provided for you an entrance into the eternal kingdom of our Lord and Savior Jesus Christ. (2 Peter 1:11 ESV)
It is clear that there is a Kingdom to enter and the King is Jesus Christ. He has made a way for us; He is the way into this kingdom. He has done all that is necessary for us to enter now. All because of the Love of God for humanity.
HISTORY and the book of Daniel Chapter 2, the bible talks about a King called Nebuchadnezzar. He saw a statue in his dream. God interpreted it to him using His prophet called Daniel.
The interpretation made in the sixth century B.C precisely predicted the great kingdoms that would reign over the world until the reign of King Jesus which will be eternal. These included Babylon (609-539 BC), Medo-Persia (539-331 BC), Greece (331-168 BC), Rome (168-476 AD), Europe (476 AD till the establishment of Kingdom of Christ. Just as these kings reigned so shall our Lord Jesus reign in a real kingdom.
The writings of the bible are matched by history which cannot be disputed. But you may ask how do we enter?
Jesus answered him, "Truly, truly, I say to you, unless one is born again he cannot see the kingdom of God." (John 3:3 ESV); Jesus answered, "Truly, truly, I say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God. (John 3:5 ESV)
This simply means we are born of the Word which is effected by God's Spirit. When we accept and confess with our mouth and BELIEVE that Jesus is Lord, that He died for us and resurrected for our salvation, we are born again. (Romans 10:8-10)
Whoever has the Son has life; whoever does not have the Son of God does not have life. I write these things to YOU WHO BELIEVE in the name of the Son of God that you may know that you have ETERNAL LIFE. (1 John 5:12-13 ESV)
KINGDOM CITIZENS LIVE RIGHT WITH YOU AND THE LIFE THEY HAVE IS ETERNAL.
