Outside of some scheming life insurance reason I can find almost no practical use for knowing ones approximate time of death.
There is a reason the good Lord kept such information from us. Who would not likely develop acute and perhaps incapacitating anxiety with such knowledge and more so as that time drew near? Here’s what I do know. It is 100% certain that I am going to die. Knowing the day or the hour should not affect the manner in which I live my life. If it did, then something is significantly wrong with my approach to life and the time I am allotted.
The destruction and mayhem caused by people not wanting to die at their allotted time would be horrendous. There would always be someone willing to kill another or cause indirectly/accidently the death of another while trying to remain past the Lord’s given time to them.
What a nightmare that would be, yes? It would be like opening another Pandora’s Box.
