"This, too, I carefully explored. Even though the actions of godly and wise people are in God's hands, no one knows whether God will show them favor. The same destiny ultimately awaits everyone, whether righteous or wicked, good or bad, ceremonially clean or unclean, religious or irreligious. Good people receive the same treatment as sinners. and people who make promises to God are treated like people who don't.
It seems so tragic that everyone under the sun suffers the same fate. That is why people are not more careful to be good. Instead, they choose own mad course, for they have no hope. There is nothing ahead but death anyway. There is hope only for the living. As they say, "It's better to be a live dog than a dead lion!"
The living at least know they will die, but the dead know nothing. They have no further reward, nor are they remembered. Whatever they did in their lifetime - loving, hating, envying - is all long gone. They no longer play a part in anything here on earth. So go ahead. Eat your food with joy, and drink your wine with a happy heart, for God approves of this! Wear fine clothes, with a splash of cologne!" (Ecclesiastes 9:1-8 NLT)
"LORD, make me to know mine end, and the measure of my days, what it is; that I may know how frail I am. Behold, thou hast made my days as a handbreadth; and mine age is as nothing before thee: verily every man at his best state is altogether vanity." [Selah.] (Psalms 39:4-5 KJV)
Again, we must remember that Solomon here is sharing about living under the sun, which, in case you might have lost sight of that, it is referring to those that live on earth, this rotating ball that circles the sun! By the way, just in case you might have not known, but we are traveling in a circle, which takes 365 days to circle the sun, at a speed of 67,000 miles per hour to go approx. 590,000,000 miles. At the same time, this planet is spinning at a speed of 1,000 miles per hour; every 24 hours we have traveled 24,000 miles in a circle, without even knowing we moved!
Strange, but oh so exciting! God made this, designed it to function just as it does. Too bad mankind is not wound up like most everything else; we just seem to do what we want, seeing that we have a choice...
"Surely every man walketh in a vain show: surely they are disquieted in vain: he heapeth up riches, and knoweth not who shall gather them. And now, Lord, what wait I for? my hope is in thee. Deliver me from all my transgressions: make me not the reproach of the foolish. I was dumb, I opened my mouth; because thou didst it. Remove thy stroke away from me: I am consumed by the blow of thy hand. When thou with rebukes dost correct man for iniquity, thou makest his beauty to consume away like a moth: surely every man is vanity." [Selah.] (Psalms 39:6-11 KJV)
