The Kingdom of God
The Kingdom of God was initiated with peace and righteousness when Jesus came to save us from sin. The gospel of His Kingdom is salvation by the grace of God through faith in Jesus as a crucified and risen Redeemer.
Christ's Kingdom in this present age is a powerful force, an everlasting kingdom established in the death, resurrection and judgment of Christ.
The final stage of the Kingdom of God is the eternal kingdom that is to be ushered in at the second coming of Christ.
John 14:1-3 Let not your heart be troubled: ye believe in God believe also in me. In my Father's house are many mansions; if it were not so, I would have told you. I go to prepare a place for you. And if I go and prepare a place for you, I will come again and receive you unto myself, that where i am there ye may be also.
