If the earth is fit for laughter then surely heaven is filled with it. Heaven is the birthplace of laughter.
If I am not allowed to laugh in heaven, I don't want to go there.
You have as much laughter as you have faith.
The Gospel is nothing less than laughter and joy.
The heart overflows with gladness, and leaps and dances for the joy it has found in God. In this experience the Holy Spirit is active, and has taught us in the flash of a moment the deep secret of joy. You will have as much joy and laughter in life as you have faith in God.
