That is said to the goats, the ones on His Left hand. unbelievers.
32“All the nations will be gathered before Him; and He will separate them from one another, as the shepherd separates the sheep from the goats; 33and He will put the sheep on His right, and the goats on the left. NASB Matt 25:32-33
Different in species is curious. The new creation in Christ comes to mind.
His servants?
These were His servants. Notice they call Him Lord.
Let's look at the context starting from verse 1.
"Then the kingdom of heaven shall be likened to ten virgins who took their lamps and went out to meet the bridegroom.
11 Afterward the other virgins came also, saying, 'Lord, Lord, open to us!' 12 But he answered and said, 'Assuredly, I say to you, I do not know you.' 13 Watch therefore, for you know neither the day nor the hour in which the Son of Man is coming.
Why would Jesus be concerned with the world watching for His Coming?
and again -
14 "For the kingdom of heaven is like a man traveling to a far country, who called his own servants and delivered his goods to them.
28 Therefore take the talent from him, and give it to him who has ten talents. 29 For to everyone who has, more will be given, and he will have abundance; but from him who does not have, even what he has will be taken away. 30 And cast the unprofitable servant into the outer darkness. There will be weeping and gnashing of teeth.' 31 "When the Son of Man comes in His glory, and all the holy angels with Him, then He will sit on the throne of His glory. 32 All the nations will be gathered before Him, and He will separate them one from another, as a shepherd divides his sheep from the goats.
33 And He will set the sheep on His right hand, but the goats on the left. 34 Then the King will say to those on His right hand, 'Come, you 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; 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 drink?
The righteous ones recognize Him as Lord.
41 Then He will also say to those on the left hand, 'Depart from Me, you cursed, into the everlasting fire prepared for the devil and his angels: 42 for I was hungry and you gave Me no food; I was thirsty and you gave Me no drink; 43 I was a stranger and you did not take Me in, naked and you did not clothe Me, sick and in prison and you did not visit Me.' 44 Then they also will answer Him, saying, '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?'
These unrighteous servants of His also recognize Him as Lord and understand MINISTRY...
Those on His Left hand are His servants who were unprofitable, meaning they did not produce fruit. they claim to know Him as Lord, but in works they deny Him.
It don't find any reference to the world mentioned in Matthew 25.
Verse 30 clearly says unprofitable servant... And cast the unprofitable servant into the outer darkness.
