Ecclesiastes 7:14

In the day of prosperity be joyful, but in the day of adversity consider: God also hath set the one over against the other, to the end that man should find nothing after him.
12

For wisdom is a defence, and money is a defence: but the excellency of knowledge is, that wisdom giveth life to them that have it.

13

Consider the work of God: for who can make that straight, which he hath made crooked?

14

In the day of prosperity be joyful, but in the day of adversity consider: God also hath set the one over against the other, to the end that man should find nothing after him.

15

All things have I seen in the days of my vanity: there is a just man that perisheth in his righteousness, and there is a wicked man that prolongeth his life in his wickedness.

16

Be not righteous over much; neither make thyself over wise: why shouldest thou destroy thyself?

Counter-Arguments

The strongest case that this verse does not belong in this theme.

Time-Bound Fulfillment

The verse speaks of general conditions of prosperity and adversity, not specific prophecies with defined durations or their recognition upon fulfillment. The phrase "to the end that man should find nothing after him" refers to the unknowability of future events or divine purpose, rather than the fulfillment of time-bound prophecies.
