I believe you will find that heaven is what our lives turn in to when we repent of our sin. I suspect there will be those who protest vigorously, but for those who have ears to hear, try it, if you haven’t already. Another name for it would be New Jerusalem.
Luk 17:20 And when he was demanded of the Pharisees, when the kingdom of God should come, he answered them and said, The kingdom of God cometh not with observation:
Luk 17:21 Neither shall they say, Lo here! or, lo there! for, behold, the kingdom of God is within you.
It is true that the kingdom of God comes without observation,we will not see the kingdom of God on earth as a physical dominion,at least not until the millennial reign,and the kingdom of God is within you when you receive the Spirit,for instead of a physical dominion the kingdom of God is displayed through the saints to the world by the Holy Spirit,them acting like Christ.
But the New Jerusalem is an actual place,and the saints final destination for all eternity,and the kingdom of God in the spiritual.

Rev 21:12 And had a wall great and high, and had twelve gates, and at the gates twelve angels, and names written thereon, which are the names of the twelve tribes of the children of Israel:

It is obvious that the New Jerusalem is a real place that is spiritual,the place that Jesus went to prepare for the saints that where He is at the saints may also be there,a new heaven,and a new earth,where sin has never been,and sin will never be,and the 12 tribes of Israel,and the 12 apostles of the Lamb,are written in that city,that does not need light,for God in the glorified body of the man Christ Jesus,the throne of God and the Lamb,will shine through that glorified body,and light the New Jerusalem.
