Matthew 25:31-46:
31 “When the Son of man comes in his glory, and all the angels with him, then he will sit down on his glorious throne. 32 All the nations will be gathered before him, and he will separate people one from another, just as a shepherd separates the sheep from the goats. 33 And he will put the sheep on his right hand, but the goats on his left.
34 “Then the King will say to those on his right: ‘Come, you who have been blessed by my Father, inherit the Kingdom prepared for you from the founding of the world. 35 For I became hungry and you gave me something to eat; I was thirsty and you gave me something to drink. I was a stranger and you received me hospitably; 36 naked and you clothed me. I fell sick and you looked after me. I was in prison and you visited me.’ 37 Then the righteous ones will answer him with the words: ‘Lord, when did we see you hungry and feed you, or thirsty and give you something to drink? 38 When did we see you a stranger and receive you hospitably, or naked and clothe you? 39 When did we see you sick or in prison and visit you?’ 40 In reply the King will say to them, ‘Truly I say to you, to the extent that you did it to one of the least of these my brothers, you did it to me.’
41 “Then he will say to those on his left: ‘Go away from me, you who have been cursed, into the everlasting fire prepared for the Devil and his angels. 42 For I became hungry, but you gave me nothing to eat; and I was thirsty, but you gave me nothing to drink. 43 I was a stranger, but you did not receive me hospitably; naked, but you did not clothe me; sick and in prison, but you did not look after me.’ 44 Then they too will answer with the words: ‘Lord, when did we see you hungry or thirsty or a stranger or naked or sick or in prison and did not minister to you?’ 45 Then he will answer them, saying: ‘Truly I say to you, to the extent that you did not do it to one of these least ones, you did not do it to me.’ 46 These will depart into everlasting cutting-off, but the righteous ones into everlasting life.” (NWT)
2 Thessalonians 1:6-9:
"We are obligated always to give thanks to God for you, brothers. This is fitting, because your faith is growing exceedingly and the love of each and every one of you is increasing toward one another. 4 As a result we ourselves take pride in you among the congregations of God because of your endurance and faith in all your persecutions and the hardships that you are suffering. 5 This is a proof of the righteous judgment of God, leading to your being counted worthy of the Kingdom of God, for which you are indeed suffering.
6 This takes into account that it is righteous on God’s part to repay tribulation to those who make tribulation for you. 7 But you who suffer tribulation will be given relief along with us at the revelation of the Lord Jesus from heaven with his powerful angels 8 in a flaming fire, as he brings vengeance on those who do not know God and those who do not obey the good news about our Lord Jesus. 9 These very ones will undergo the judicial punishment of everlasting destruction from before the Lord and from the glory of his strength" (NWT)
That pretty much covers people of "all the nations". Those who 'do not know God' choose not to know him.....and those who 'know him but fail to obey him' suffer the same fate.
