Matthew 25:31-46 makes it clear that it will be all of the saved, which are those who will inherit eternal life in the kingdom prepared for us from the foundation of the world (Matt 25:34,46) and all of the lost, which are those who will be cast into everlasting fire prepared for the devil and his angels for everlasting punishment (Matt 25:41,46).""Nope. Matthew 25:31-46 has not yet happened,""
100% agreed.
""No one has yet appeared before the judgment seat of Christ."" 1 Cor 3:10-15, 2 Cor 5:10
Since that is the teaching of Paul, who do you believe will appear there ?
You missed one reference to the judgment seat of Christ.
Romans 14:10 But why do you judge your brother? Or why do you show contempt for your brother? For we shall all stand before the judgment seat of Christ. 11 For it is written: “As I live, says the Lord, Every knee shall bow to Me, And every tongue shall confess to God.”
12 So then each of us shall give account of himself to God.
In verse 11 here, Paul references this prophecy...
Isaiah 45:22 “Look to Me, and be saved, All you ends of the earth! For I am God, and there is no other. 23 I have sworn by Myself; The word has gone out of My mouth in righteousness, And shall not return, That to Me every knee shall bow, Every tongue shall take an oath. 24 He shall say, ‘Surely in the Lord I have righteousness and strength. To Him men shall come, And all shall be ashamed Who are incensed against Him.
It is not just believers who will appear before the judgment seat of Christ, as some people think. Every person, saved and lost, will bow before Jesus Christ when He is in His judgment seat/throne, including those "who are incensed against Him". And they will all acknowledge that He is Lord.
Philippians 2:9 Therefore God also has highly exalted Him and given Him the name which is above every name, 10 that at the name of Jesus every knee should bow, of those in heaven, and of those on earth, and of those under the earth, 11 and that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father.
