Wrong interpretation. Nowhere are Gentiles or Jews noted. And these are not nations. It is quite clear that it refers to individual persons. And even if it is nations, then Israel is a goat nation because it is starving people to death. And are you saying that Jesus would be okay with Netanyahu starving thousands of Palestinian children to death? Are you sure of that. Are you okay with it? Trump apparently is. It’s okay with “the King” to starve children to death? Are they not “the least of these”?
And did God approve of the slavery of blacks that occurred before the Civil War? Why are you avoiding that question?
The Second Coming: (Matt. 25:31) "When the Son of man shall
come in his glory, and all the holy angels with him, then shall he sit upon the throne of his glory:". After His return all the nations are gathered before Him. "(Matt. 25:32) "And before him shall be gathered all
nations: and he shall separate them one from another, as a shepherd divideth his sheep from the goats. And he shall set the sheep on his right hand, but the goats on the left."
The term 'Gentiles' or 'Nations' when used in the Bible speaks to the nations other than Israel, other than Jewish. 'goy' in the Old Testament and 'ethnos' in the New Testament.
This judgement of the sheep and goat nations is after the Second Coming of Christ. Israel and the world have just come through the Tribulation period on earth where tremendous destruction and persecution of the Jews have taken place. Jesus warned His disciples, who were Jews, that when they see the abomination of desolation stand in the Temple, as Daniel predicted they need to flee immediately. (Matt. 24:15-20) Because: "For then shall be
great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be."
And then after that tribulation returns Jesus Christ. (Matt. 24:29) "Immediately
after the tribulation of those days shall the sun be darkened, and the moon shall not give her light, and the stars shall fall from heaven, and the powers of the heavens shall be shaken: And then shall
appear the sign of the Son of man in heaven; and then shall all the tribes of the earth mourn, and they shall see the
Son of man coming in the clouds of heaven with power and great glory."
Thus, the judgement of the nations, (Matt. 25:32) occurs after Christ's 2nd Coming. It has nothing to do with Christians, as you are trying to make it. It has to do with the way the Gentile nations treated the Jews during that Tribulation period.
Again, your use of (Matt. 25:40-46) is in the wrong time period and directed at the wrong people.
God doesn't disapprove of slavery. There are always good and bad slave owners as there are good and bad employers. I'm not avoiding the question. I have told you that God instituted slavery.
