'New Creation' in the Bible

"I solemnly tell you," replied Jesus, "that in the New Creation, when the Son of Man has taken His seat on His glorious throne, all of you who have followed me shall also sit on twelve thrones and judge the twelve tribes of Israel.

So if any one be in Christ, there is a new creation; the old things have passed away; behold all things have become new:

For in Christ Jesus neither is circumcision anything, nor uncircumcision; but new creation.

a renewal in which there is no [distinction between] Greek and Jew, circumcised and uncircumcised, [nor between nations whether] barbarian or Scythian, [nor in status whether] slave or free, but Christ is all, and in all [so believers are equal in Christ, without distinction].

'tis he that has voluntarily renew'd us by the oracles of truth, that we might be the first converts of the new creation.
