God said:
The refrain of life as sung on Earth is loss and gain with an emphasis on loss, so it appears.
Who goes to court to sue for a mistaken gain in income? No one sues a car company for the car's exceeding the anticipated gas mileage. No one sues anyone for delivering an unexpected third baby, nor would they!
No one complains about winning a billion-dollar lottery. No one complains about finding a $20.00 bill on the sidewalk. No one complains about gain unless it's a gain in weight or clutter.
There is plenty of complaint when someone loses his eyesight. You would too, understandably, yet where was all the gratitude for your eyesight all the years when you had the good use of your eyes?
In these days, age is often seen as a decline from strength, yet age often is a gain of wisdom and, sometimes, a gain of great wisdom and great goodness of heart. You really can't say you haven't learned something during your ride on Earth.
I am making a case for abstinence from sense of loss, abstinence from your seeing loss, seeing the absence of someone dear to you absconded and kidnapped to Heaven as an offense to you. Actually, you may see loss as something you own and of great value being stolen from you by stealth and by no right. You wouldn't mind being the exception to the rule and be immortal even in terms of this physical life on Earth.
There are two things to remember here, dear ones. There are reasons for the term of your body. What you see as death has merit behind it.
