A WITNESS TO ALL THE NATIONS.
"Go therefore and make disciples of people of all the nations, baptizing them in the Name of the Father and of the Son and of the Holy Spirit, teaching them to observe all the things I have commanded you. And look! I am with you all the days until the conclusion of the system of things." (From Matt 28:18-20).
"And this good news of the Kingdom will be preached in all the inhabited earth for a witness to all the nations; and then the end will come." (Matt 24:14).
"But in the days of the sounding of the seventh angel, when he is about to blow his trumpet, the sacred secret of God according to the good news which he declared to his own slaves the prophets is indeed brought to a finish." (1) (Rev 10:7).
"To you who suffer tribulation, relief along with us at the revelation of the Lord Jesus from heaven with his powerful angels in a flaming fire, as he brings vengeance upon those who do not know God and those who do not obey the good news about our Lord Jesus. These very ones will undergo the judicial punishment of everlasting destruction from before the Lord and from the glory of his strength, at the time he comes to be glorified in connection with his holy ones and to be regarded in that day with wonder in connection with all those who exercised faith, because the witness we gave met with faith among you." (2 Thess 1:7-10).
(1) The opportunity to be obedient to God through the exercise of faith in the "good news" of The Christ ceased when people of the nations spiritually "trampled" upon members of the anointed "temple" class of God on earth.
