Heaven is the place where God lives in all His glory. The Lord Jesus said, I am going to prepare a place for you. And after I go to prepare a place for you, I will come back and take you to myself, so that you will be where I am (john 14;2,3). It is a marvelous place, where He will wipe away all tears from their eyes. There will be no more death, no more grief or crying or pain. The old things have disappeared. There shall be no more night because the Lord God will be their light. Rev. 21;4, 22;5.
It is a sacred place, nothing that is impure will enter the city,nor any one who does shameful things or tell lies. Only those whose names are written in the Lamb’s book of the living will enter the city Rev 21:27.
There is only one way to Heaven, I am the way, the truth and the life no one goes to the Father except by me .(John 14;6). Salvation is to be found through Him alone, in all the world there is no one else whom God has given who can save us. (Acts 4;12)
