Ecclesiastes 2:16-23 - Without God Everything Is Pointless
16 Certainly no one will remember the wise man or the fool in {future generations}. When [future] days come, both will have been forgotten already. How [is it that] the wise man dies the same as the fool? 17 So I hated life because the work done under the sun [is] grievous to me. For everything [is] vanity and chasing wind!
18 So I hated all my toil with which I have toiled under the sun, for I must leave it behind to someone who will be after me. 19 And who knows [whether] he will be wise or foolish? Yet he will exercise control of all [the fruit of] my toil with which I toiled wisely under the sun. This also [is] vanity! 20 So {I began to despair} of all the toil with which I toiled under the sun. 21 For although a person may toil with great wisdom and skill, he must leave his reward to someone who has not toiled for it. This also [is] vanity and a great calamity. 22 For what does a person receive for all his toil and in the longing of his heart with which he toils under the sun? 23 All his days [are] painful, his labor [brings] grief, and his heart cannot rest at night. This also [is] vanity!
