Below is a list of hymns about heaven that I have managed to source for you.
A Child of the King
Be Still, My Soul
Be Thou My Vision
Blessed Assurance
Day by Day
Faith Is the Victory
Goin’ Up Yonder
Going Home
He the Pearly Gates Will Open
Heaven Came Down
Heaven is My Home
Heaven’s Now My Home
I Shall Wear A Crown
I’m A Child of the King
I’ll Fly Away
In the Sweet By and By
It Is Well with My Soul
Mansion on a Hilltop
Nearer My God to Thee
O That Will Be Glory
Praise, My Soul, the King of Heaven
Precious Memories
Rock of Ages
Soon And Very Soon
Surely Goodness and Mercy
Swing Low Sweet Chariot
There Is Coming A Day
Till We Meet Again
Victory in Jesus
We Shall Behold Him
What A Day That Will Be
When I See Jesus
When the Roll is Called Up Yonder
When They Ring the Golden Bells
When We All Get to Heaven
Will the Circle Be Unbroken
Worthy Is The Lamb
