The billboard would have been considerably longer if the list full list of who comes under His judgment was to be displayed.
Re:1:7:
Behold,
he cometh with clouds;
and every eye shall see him,
and they also which pierced him:
and all kindreds of the earth shall wail because of him.
Even so,
Amen.
Muslims would seem to qualify as the 'lesser' in the verses below and it would be Christians who God will hold to the highest standards and judging by just the last 500 years there will be more Muslims alive for the 1,000 year reign and (false) Christians.
Lu:12:43-49:
Blessed is that servant,
whom his lord when he cometh shall find so doing.
Of a truth I say unto you,
that he will make him ruler over all that he hath.
But and if that servant say in his heart,
My lord delayeth his coming;
and shall begin to beat the menservants and maidens,
and to eat and drink,
and to be drunken;
The lord of that servant will come in a day when he looketh not for him,
and at an hour when he is not aware,
and will cut him in sunder,
and will appoint him his portion with the unbelievers.
And that servant,
which knew his lord's will, and prepared not himself,
neither did according to his will,
shall be beaten with many stripes.
But he that knew not, and did commit things worthy of stripes,
shall be beaten with few stripes.
For unto whomsoever much is given,
of him shall be much required:
and to whom men have committed much,
of him they will ask the more.
I am come to send fire on the earth;
and what will I, if it be already kindled?
Re:2:3-5:
And hast borne,
and hast patience,
and for my name's sake hast laboured,
and hast not fainted.
Nevertheless I have somewhat against thee,
because thou hast left thy first love.
Remember therefore from whence thou art fallen,
and repent,
and do the first works;
or else I will come unto thee quickly,
and will remove thy candlestick out of his place,
except thou repent.
