...about the events regarding the return of Jesus at the time of the end. Obviously the gospel had not been spread to all nations of world in the first century.
Matthew 24:14 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.
Well, Somebody must have forgot to tell that to Paul, who believed and taught the exact opposite of what you are claiming:
Colossians 1:5-6 because of the hope which is laid up for you in heaven, of which you heard before in the word of the truth of the gospel, 6 which has come to you,
as it has also in all the world, and is bringing forth fruit, as it is also among you since the day you heard and knew the grace of God in truth;
Colossians 1:23 if indeed you continue in the faith, grounded and steadfast, and are not moved away from the hope of the gospel which you heard, which
was preached to every creature under heaven, of which I, Paul, became a minister.
In
Matthew 24:14, the Greek word for preached is kerusso, it is in the future tense. But in
Colossians 1:23 the same word kerusso is in the aorist tense (past). Jesus said that it is to be preached and Paul says in AD 62, that it has been preached to every creature. Paul also said that the faith of the Romans was spoken of throughout the whole world.
Romans 1:8 First, I thank my God through Jesus Christ for you all, that your faith is spoken of
throughout the whole world.
Paul said that the gospel was made known to all nations.
Romans 16:25-26 Now to Him who is able to establish you according to my gospel and the preaching of Jesus Christ, according to the revelation of the mystery kept secret since the world began 26 but now has been made manifest, and by the prophetic Scriptures
has been made known to all nations, according to the commandment of the everlasting God, for obedience to the faith;
Many today say that the gospel has not been preached to all the world and
Matthew 24:14 has not yet been fulfilled. The Bible says that all the nations of the world heard the gospel preached before AD 70. Who are you going to believe? To deny that
Matthew 24:14 has been fulfilled is to deny the clear statements of God's Holy Word; it is to call God a liar.
When faced with choosing which of these two polar opposite views being taught is true and correct, that of the Divinely, infallibly Inspired 1st century apostle Paul, or that or Random, fallible, 21st century internet guy Douggg, My money is on the Apostle being correct, and Douggg being wrong.
The Bible says is, I believe it, That settles it.
