Those who live in grace are freed from the necessity of taking themselves, their circumstances, their morality and opinions, their piety and beliefs, too seriously. They are free to laugh and play as children of God. As important as repentance is, we are not saved by our much weeping, any more than we are saved by acts of penitence. And the expression of salvation freely given and received is not weeping but laughter, or at least a weeping become laughter. Laughter and lightheartedness, at their fullest and freest, are the gift of divine grace.
~Conrad Hyers, And God Created Laughter
