The happiness of the world is only a sleeping flower, or as shade inevitably passes. If the world makes happy a day, it can also make it sad all the time.
It's not always that the people we love are always with us.
We always hoped he would always be there for us. When we are sick, we are weak, so that we are not rich. Maybe the person we love cares about us, he loves us, but that's just the love of man, the care of humans. When we are sick to the one who loves us he will not be able to take away our pain, cannot heal us, because we know that human affection is limited and his care is limited, his strength is limited.
But remember we have a God who always loves us whose love is limitless and He is also the One who heals His faithful servants.
