He has set eternity in the hearts of men

Ecclesiates 3 9 What profit hath he that worketh in that wherein he laboureth? 10 I have seen the travail, which God hath given to the sons of men to be exercised in it. 11 He hath made every thing beautiful in his time: also he hath set the world in their heart, so that no man can find out the work that God maketh from the beginning to the end.  -kjv 9 What do workers gain from their toil? 10 I have seen the burden God has laid on the human race. 11 He has made everything beautiful in its time. He has also set eternity in the human heart; yet no one can fathom what God has done from beginning to end.  -niv 9 What does the worker gain from his struggles? 10 I have seen the task that God has given people to keep them occupied. 11 He has made everything appropriate in its time. He has also put eternity in their hearts, but man cannot discover the work God has done from beginning to end.   -hcsb Observation: God has placed a God-shaped vacuum in people's heart but they are not able to understand it. In kjv, it says  the heart of man is blinded by the desires of this world, which is opposite to that of God
