Well, the things you are referring to basically refer to the New Testament age broadly speaking, in which we now live. Jesus Christ is risen today and ascended to the right hand of God the Father. Now we wait for his return in glory. In this sense, it is the last day. This time is also spoken of in Daniel the prophet, where it says in Daniel 12 the following words:
>8 And I heard, but I understood not: then said I, O my Lord, what shall be the end of these things?
>9 And he said, Go thy way, Daniel: for the words are closed up and sealed till the time of the end.
And so we see that now said time has come, seeing as the parallel to this is now found in Revelation 22:
>10 And he saith unto me, Seal not the sayings of the prophecy of this book: for the time is at hand.
Hence, Paul could tell the churches the following in Romans, "And that, knowing the time, that now it is high time to awake out of sleep: for now is our salvation nearer than when we believed."
And again, in Acts 13:46-48, "It was necessary that the word of God should first have been spoken to you: but seeing ye put it from you, and judge yourselves unworthy of everlasting life, lo, we turn to the Gentiles. For so hath the Lord commanded us, saying, I have set thee to be a light of the Gentiles, that thou shouldest be for salvation unto the ends of the earth."
And again in Hebrews 10:23-25, "Let us hold fast the profession of our faith without wavering; (for he is faithful that promised;) And let us consider one another to provoke unto love and to good works: Not forsaking the assembling of ourselves together, as the manner of some is; but exhorting one another: and so much the more, as ye see the day approaching."
