41
The Son of Man will send out His angels, and they will weed out of His kingdom every cause of sin and all who practice lawlessness.
Most folks think this refers to purging the Church of 'Tares'.
What is "His Kingdom" in this verse?
"
All will Experience the Tribulation
God's people, those who have washed their robes in the blood of the Lamb, have to go through the tribulation. “For the Son of man shall come in the glory of his Father with his angels; and then he shall reward every man according to his works” (Matthew 16:27).
God is just: He will pay back trouble to those who trouble you and give relief to you who are troubled, and to us as well. This will happen when the Lord Jesus is revealed from heaven in blazing fire with his powerful angels (2 Thessalonians 1:6-7 NIV).
According to these texts, relief for the righteous and recompense for the wicked take place at the same time—at the return of Christ.
This is what Jesus told His disciples about the end-‐time tribulation:The Son of Man will send out His angels, and they will gather out of His kingdom all things that offend, and those who practice lawlessness, and will cast them into the furnace of fire. There will be wailing and gnashing of teeth. Then the righteous will shine forth as the sun in the kingdom of their Father
(Matthew 13:41-43 NKJV).
Just like the wheat and the tares Jesus describes in Matthew 13, the wicked and the just will stay together until the return of Christ. When Old Testament Israel was delivered from the bondage of Egypt, the plagues did not fall when the Israelites were already gone. They were present and witnessed the events, being subjected to the first three plagues themselves (Exodus 8-‐12).
God divinely protected the Israelites from the effects of the last seven plagues in Egypt, just as He will divinely protect His people from the effects of the last seven plagues at the end of time (Revelation 3:10-‐13). God's people are urged to hold on until He comes. They are not taken to heaven before these events.
The glory of Christ's Second Coming leaves no hint of secrecy, and the judgment of the wicked and the righteous will happen at the same time. The return of Christ is the blessed hope of the people of God: Jesus is to be revealed (1 Corinthians 1:7; 1 Peter 1:7,13; 4:13)."
