The setting of Matthew 25:31-33 is about Jesus' coming Glory Time, or the Time of Separation to take place on Earth.What is the context of all of these chapters? It is easy to quote but harder to explain, I believe. Especially if one doesn't know the context.
Jesus as King of God's Kingdom will separate living people.
The figurative humble ' sheep ' (verse 37) have a favorable judgement.
The figurative haughty ' goats ' have an adverse judgement.
The 'sheep' (Revelation 7:9,14) can remain alive on Earth and be here to see calendar Day One of Jesus' coming 1,000-year governmental reign over Earth.
The ' goats' ( 2 Thessalonians 1:9) are punished with: everlasting destruction.
The 'sword-like executional words from Jesus' mouth ' will rid the earth of the wicked - Isaiah 11:3-4; Rev. 19:14-15.
ALL the wicked will be ' destroyed forever ' according to Psalms 92:7; Psalms 104:35; Proverbs 2:21-22.
