When I was young we sang a song regarding heaven entitled "Where we Will Never Grow Old." Dying and going to heaven was not a primary joy. I was young and entergetic. I had work to do, a family to raise and labors for my God.
Now I am 86, my work is virtually finished, my family is raised and mainly my labor for God is over. Heaven means a lot more. We will never again grow old, but stay forever young, as Jesus did in His resurrected body.
It means heaven takes on a meaning that was not there during my youth.
