'Climax' in the Bible

Now these things happened to them as an example and warning [to us]; they were written for our instruction [to admonish and equip us], upon whom the ends of the ages have come.

with regard to the fulfillment of the times [that is, the end of history, the climax of the ages]—to bring all things together in Christ, [both] things in the heavens and things on the earth.

Then I saw another sign in heaven, great and wonderful [a warning of terrifying and horrible events]: seven angels who had seven plagues (afflictions, calamities), which are the last, because with them the wrath of God is finished [that is, it is completely expressed and reaches its zenith].
