It should be clear to all Christians (at least) that we are in the Church Age.
And this gospel of the kingdom shall be preached in all the world for a witness unto all nations; and then shall the end come. (Matthew 24:14)
Glad you brought up Matt:
Col 1:23 if indeed you continue in the faith firmly established and steadfast, and not moved away from the hope of the gospel that you have heard,
which was proclaimed in all creation under heaven, and of which I, Paul, was made a minister
Rom 10:18 But I say, surely they have never heard, have they? Indeed they have; But I say, surely they have never heard, have they? Indeed they have; “
THEIR VOICE HAS GONE OUT INTO ALL THE EARTH, AND THEIR WORDS TO THE ENDS OF THE WORLD.”
Looks like Paul is saying the conditions for "the end" were met during his ministry which confirms my dissertation in the opening post.
