Notice the command to preach the gospel to all the world, also notice the greek words used: Matt.24:14 And this gospel of the kingdom shall be preached in the whole world ( oiÎkoumeÑnh )for a testimony unto all the nations ( eáqnov ); and then shall the end come. Mark 16:15 And he said unto them, Go ye into all the world ( ko/smov ), and preach the gospel to the whole creation .(ktiðsiv) Matt.28:19 Go ye therefore, and make disciples of all the nations (eáqnov ), baptizing them into the name of the Father and of the Son and of the Holy Spirit: Acts 1:8 But ye shall receive power, when the Holy Spirit is come upon you: and ye shall be my witnesses both in Jerusalem, and in all Judaea and Samaria, and unto the uttermost part of the earth ( gh=), All fulfilled in the 1st century: Col.1:6 which is come unto you; even as it is also in all the world ( ko/smov ) bearing fruit and increasing, as it doth in you also, since the day ye heard and knew the grace of God in truth; Col 1:23 if so be that ye continue in the faith, grounded and stedfast, and not moved away from the hope of the gospel which ye heard, which was preached in all creation ( ktiðsiv )under heaven; whereof I Paul was made a minister Romans 16:26 but now is manifested, and by the scriptures of the prophets, according to the commandment of the eternal God, is made known unto all the nations ( eáqnov) unto obedience of faith: Romans 10:18 But I say, Did they not hear? Yea, verily, Their sound went out into all the earth ( gh=), And their words unto the ends of the world ( oiÎkoumeÑnh ). So next time you hear your preacher say that the gospel must go out into the world before Christ can return, simply open your bible to these passages and wonder, "what else happened in the 1st century that my preacher doesn't know about". Matt.24:14 And this gospel of the kingdom shall be preached in the whole world for a testimony unto all the nations; and then shall the end come .
