I have lived a long life. After going through many years of existence the times of enjoyment, happiness, bliss, contentment and elation are very fleeting moments. For example, when you buy a new car, a new house, or a new wife (!) the happiness of these events fades quickly.
In contrast, the times of pain, suffering, anguish, tragedy, accidents, sickness, turmoil, etc. etc. are long-lasting. Many times more lasting than the above moments of elation.
I believe this is the human condition that no one can escape. And it’s a great mystery of life.
Oozing Wisdom 
“Things and circumstances can give us happiness, but only an inner wellspring can bring forth joy. Joy can be felt in the midst of tragedy and loss; yes, joy can be experienced through tears. And joy is what Christ came to bring to all those who would believe in Him.”
