This Generation: 1Pe 2:5 KJV  Ye also, as lively stones, are built up a spiritual house, an holy priesthood, to offer up spiritual sacrifices, acceptable to God by Jesus Christ.

1Co 10:11 Now all these things happened unto them for examples: and they are written for our admonition, upon whom the ends of the world [eon] are come.Heb 1:2 Hath in these last days spoken unto us by his Son , whom he hath appointed heir of all things, by whom also he made the worlds; [eon] for these are the two covenants; For if that first covenant had been faultless, then should no place have been sought for the second.(Heb 8:13 KJV) In that he saith, A new covenant, he hath made the first old. Now that which decayeth and waxeth old is ready to vanish away. I think this is what is meant by the worlds above the two covenants"
