Why does Paul mention ENDS of the world?
My understanding of that is based on the following, from it's passages...based on two principles.
Looking up those words in the original language; along with the application of the principle I'll post, in a moment...
The word "world" there is also plural, and refers to "ages" - "the ends (plural) of the ages" (plural) is the intended sense.
What ends of the ages is he referring to, is then much more easier to solve for.
And the sense is that those things that happened in those past ages had each ended up in resulting wisdom thru their example as ends (end results) highly useful in learning from, towards the application of their lessons, in the here and now.
They had each ended up being examples, one might do well to attempt learn some applicable wisdom from, towards applying, in the here and now.
That is based on another guiding principle, which is the simple principle of asking oneself the question "what was Paul talking about, when he then added to that what he then added to it, after it?"
1 Corinthians 10:1 Moreover, brethren, I would not that ye should be ignorant, how that all our fathers were under the cloud, and all passed through the sea;
10:5 But with many of them God was not well pleased: for they were overthrown in the wilderness.
10:6 Now these things were our examples, to the intent we should not lust after evil things, as they also lusted.
Could you repeat that, please...
10:11 Now all these things happened unto them for ensamples: and they are written for our admonition, upon whom the ends of the world are come.
Okay; got it. In other words, one can learn from said past results.
10:12 Wherefore let him that thinketh he standeth take heed lest he fall.
For as said past events as examples had repeatedly proven....
10:13 There hath no temptation taken you but such as is common to man: but God is faithful, who will not suffer you to be tempted above that ye are able; but will with the temptation also make a way to escape, that ye may be able to bear it.
10:14 Wherefore, my dearly beloved, flee from idolatry.
10:15 I speak as to wise men; judge ye what I say.
