In John 5:
24"I tell you the truth, whoever hears my word and believes him
who sent me has eternal life and will not be condemned; he has
crossed over from death to life. 25I tell you the truth, a time is
coming and has now come when the dead will hear the voice of the
Son of God and those who hear will live. 26For as the Father has
life in himself, so he has granted the Son to have life in himself.
27And he has given him authority to judge because he is the Son of
Man.
28"Do not be amazed at this, for a time is coming when all who are
in their graves will hear his voice 29and come out—those who have
done good will rise to live, and those
who have done evil will rise to be condemned. 30By myself I
can do nothing; I judge only as I hear,
and my judgment is just, for I seek not to please myself but
him who sent me.
So Jesus judges and he condemns.
Matthew 25:
31"When the Son of Man comes in his glory, and all the angels
with him, he will sit on his throne in heavenly glory. 32All the
nations will be gathered before him, and he will separate the
people one from another as a shepherd separates the sheep from the
goats. 33He will put the sheep on his right and the goats on his
left.
34"Then the King will say to those on his right, 'Come, you who are
blessed by my Father; take your inheritance, the kingdom prepared
for you since the creation of the world. 35For I was hungry and you
gave me something to eat, I was thirsty and you gave me something
to drink, I was a stranger and you invited me in, 36I needed
clothes and you clothed me, I was sick and you looked after me, I
was in prison and you came to visit me.'
37"Then the righteous will answer him, 'Lord, when did we see you
hungry and feed you, or thirsty and give you something to drink?
38When did we see you a stranger and invite you in, or needing
clothes and clothe you? 39When did we see you sick or in prison and
go to visit you?'
40"The King will reply, 'I tell you the truth, whatever you did for
one of the least of these brothers of mine, you did for me.'
41"Then he will say to those on his left, 'Depart from me, you who
are cursed, into the eternal fire prepared for the devil and his
angels. 42For I was hungry and you gave me nothing to eat, I was
thirsty and you gave me nothing to drink, 43I was a stranger and
you did not invite me in, I needed clothes and you did not clothe
me, I was sick and in prison and you did not look after me.'
44"They also will answer, 'Lord, when did we see you hungry or
thirsty or a stranger or needing clothes or sick or in prison, and
did not help you?'
45"He will reply, 'I tell you the truth, whatever you did not do
for one of the least of these, you did not do for me.'
46"Then they will go away to eternal
punishment, but the righteous to eternal life."
Jesus threatens people with eternal punishment.
PS: the burning sulphur example should be in Revelations. But these
examples should suffice, for now.
