Adam Clarke on Ecclesiastes 8:17

Then I beheld all the work of God, that a man cannot find out the work that is done under the sun - I saw it to be of such a nature -

1. That a man cannot find it out.

2. That if he labor to find it out, he shall not succeed.

3. That though he be wise - the most instructed among men, and think to find it out, he shall find he is not able. It is beyond the wisdom and power of man. How vain then are all your cavils about Providence. You do not understand it; you cannot comprehend it. Fear God!
