Resurrection, the first
'The first resurrection,' mentioned in Revelation 20:5, 6, does not mean a first resurrection, but the essence and primary part of resurrection, which is salvation and eternal life. There is only one resurrection to life. A second does not happen, and is not mentioned anywhere in the Bible.

Matthew 25:34-46
34
Then the King will tell those on his right hand, 'Come, blessed of my Father, inherit the Kingdom prepared for you from the foundation of the world;
35
for I was hungry, and you gave me food to eat. I was thirsty, and you gave me drink. I was a stranger, and you took me in.
36
I was naked, and you clothed me. I was sick, and you visited me. I was in prison, and you came to me.'
37
"Then the righteous will answer him, saying, 'Lord, when did we see you hungry, and feed you; or thirsty, and give you a drink?
38
When did we see you as a stranger, and take you in; or naked, and clothe you?
39
When did we see you sick, or in prison, and come to you?'
40
"The King will answer them, 'Most certainly I tell you, inasmuch as you did it to one of the least of these my brothers, you did it to me.'
41
Then he will say also to those on the left hand, 'Depart from me, you cursed, into the eternal fire which is prepared for the devil and his angels;
42
for I was hungry, and you didn't give me food to eat; I was thirsty, and you gave me no drink;
43
I was a stranger, and you didn't take me in; naked, and you didn't clothe me; sick, and in prison, and you didn't visit me.'
44
"Then they will also answer, saying, 'Lord, when did we see you hungry, or thirsty, or a stranger, or naked, or sick, or in prison, and didn't help you?'
45
"Then he will answer them, saying, 'Most certainly I tell you, inasmuch as you didn't do it to one of the least of these, you didn't do it to me.'
46
These will go away into eternal punishment, but the righteous into eternal life."
