What heaven is like

As He was about to leave this world, Jesus said to His disciples --

In My Father’s house are many dwelling places. If it were not so, I would have told you, because I am going there to prepare a place for you. And if I go and prepare a place for you, I will come back again and I will take you to Myself, so that where I am you may be also. - John 14:2-3

For Christians, heaven is our home.

So then, being always filled with good courage and confident hope, and knowing that while we are at home in the body we are absent from the Lord— for we walk by faith, not by sight [living our lives in a manner consistent with our confident belief in God’s promises]— we are [as I was saying] of good courage and confident hope, and prefer rather to be absent from the body and to be at home with the Lord. - 2 Corinthians 5:6-8

This city will have all the freshness, vitality and openness of the country with all the vibrancy, interdependence and relationships of a city.

For he was [waiting expectantly and confidently] looking forward to the city which has foundations, [an eternal, heavenly city] whose architect and builder is God. Now those who say such things make it clear that they are looking for a country of their own. But the truth is that they were longing for a better country, that is, a heavenly one. For that reason God is not ashamed [of them or] to be called their God [even to be surnamed their God—the God of Abraham, Isaac, and Jacob]; for He has prepared a city for them. - Hebrews 11:10,14,16

Heaven will have an endless supply and we'll meet and converse with other inhabitants.  We'll open our dwelling places to entertain people. Heaven will offer much-needed rest to the weary.

We'll reign with Christ. Reigning implies specific delegated responsibilities for those under our leadership.  We'll rule over the world and even over angels.

When God brings heaven down to the new earth --

He will wipe away every tear from their eyes; and there will no longer be death; there will no longer be sorrow and anguish, or crying, or pain; for the [a]former order of things has passed away. - Revelation 21:4

People of every tribe and nation and tongue will worship the Lamb together.

Heaven is the Christian's certain hope, a hope that can and should sustain us through life's darkest hours.  But this doesn't happen automatically.  We must choose to think about heaven and centre our lives around it --

Therefore if you have been raised with Christ [to a new life, sharing in His resurrection from the dead], keep seeking the things that are above, where Christ is, seated at the right hand of God. Set your mind and keep focused habitually on the things above [the heavenly things], not on things that are on the earth [which have only temporal value]. - Colossians 3:1-2
