One of many things that is different between believers and skeptics is their time horizons. Believers find introduction of Christianity as a permanent new direction in all of human history. Skeptics find the Christian faith to be only one of hundreds that have come and gone over the entire reach of human history.
While Christians recognize things change over time, they differ in denying this applies to their god/religion.
The Bible itself in Ecclesiastes recognizes time or timing as part of the human experience. A time to sew and a time to reap is such a powerfull metaphor it found its way into pop music, Turn, Turn, Turn.
We are all born into a culture that favors certain ideas and practices and condemns others. A couple of generations back this included the idea black people are inferior.
Another thing our culture in the west held to was that it is better to think there is but one god rather than many. The many gods fit cultures before ours because travel and communication were not common. Each area had its own god. One god fit later cultures of efficiency and growth. It fit the aspirations of the ambitious Constantine to a “T”.
Standardization of three TV channels and billions of identical Big Macs has been replaced with “have it your way.”
It seems plausible to me Ecclesiastes is hinting the time of the one god is passing and the “have it your way god” is returning.
