In thy presence is fulness of joy; at thy right hand there are pleasures for evermore. Ps. 16:11.
We understand that the people who would not be happy in heaven won't be there at all. One of the most outstanding truths that we know about heaven is that people are happy there. Have you ever wondered what makes heaven a happy place?
Now I'm sure that the boys and girls will find time for playing in heaven. For instance, I'm sure that the children will find a lot of pleasure in playing with all the animals there. It will be fun for the children, and even for some of us older ones as well, to be able to fly without having to get into an airplane first. It will be fun to try hand gliding without the hand glider, or parachute jumping without the parachute! Maybe we can even do some scuba diving in the river of life, without all that heavy equipment. And the opportunities for travel will be unlimited.
But the primary fun and happiness of heaven is not going to be in getting your own "kicks." Notice Steps to Christ, page 77: "The spirit of Christ's self-sacrificing love is the spirit that pervades heaven and is the very essence of its bliss." The reason people are happy in heaven is because they are involved in reaching out to others. And that is the secret of happiness here on this earth as well.
The happiest person in the world is the one whose life is the most centered in others, and the most miserable person in the world is the one who is most self-centered. The person whose main interest in life is trying to figure out what he can do or try next to get the most, to have the most fun, is a miserable unhappy person. Have you ever gone to some amusement center, and watched the faces of the people there, waiting in line to "have fun"? The majority of them are pretty unhappy looking. And the children who could hardly sleep the night before while waiting for the big day of "fun" are invariably grouchy all the way home.
If you are looking for happiness and fun and enjoyment, the best place to look--the only place to look--is to service, to sharing, to trying to bring the greatest happiness to those around you. This is the source of joy in this life, and will be the source of happiness in the life to come.
