Matthew 13:41-45

Mat 13:41 (KJB)
The Son of man shall send forth his angels, and they shall gather out of his kingdom all things that offend, and them which do iniquity;

Offend - Cause to fall away or to be led into sin

There shall not only be a gathering of all the believers into Heaven but there shall also be a gathering of all the sinners in the world. The sinners in the world would be those who entice the believers to sin. (Rom 1:32 KJV) Who knowing the judgment of God, that they which commit such things are worthy of death, not only do the same, but have pleasure in them that do them. This will be the great separation when the unbelievers will be separated from the believers for all eternity. Those who entice others to sin and those who continue to practice sin as unbelievers will be cast into eternal damnation after the judgment. Those angels who will gather the unbelievers will show no leniency as they are transported to be judged.

Mat 13:42 (KJB)
And shall cast them into a furnace of fire: there shall be wailing and gnashing of teeth.

The image of a furnace would well be understood because not only were there real furnaces, especially those that made different types of pottery but many there would remember the furnace in Daniel when Shadrach, Meshach, and Abednego were cast in because they refused to bow down to the golden image Nebuchadnezzar made. The situation now is that those who are taken in this sweep will not have the privilege of being saved by the Son of God. Those who are cast into the eternal fire will be there forever. According to this verse, there will be physical pain and there will be hate filled emotions toward God for this punishment. What they fail to realize is that Godís holiness and purity must be vindicated. God equates the sacrifice of His Son on Calvary with an eternity in Hell. This is because man does not possess the ability to pay for their sins since he is a sinner, making him unqualified to be their own savior. This is why they must suffer eternally in Hell.

Mat 13:43 (KJB)
Then shall the righteous shine forth as the sun in the kingdom of their Father. Who hath ears to hear, let him hear.

Once the episode with the unbelievers has become finished, then the Christians will receive their new glorified bodies and will shine as bright as the sun because they will be qualified to share in the glory of God. At present, the Christians could not shine because the glory of God would consume the bodes of flesh and that is why our bodies have to be made according to the glory they will receive. Then Jesus uses a term on the last part of this verse which concerns those who have spiritual ears. He is not speaking of those who are hearing with the physical ears but those who have been qualified by means of being born again and receiving the indwelling of the Holy Spirit, thus making the ears qualified to hear spiritual things.

Mat 13:44 (KJB)
Again, the kingdom of heaven is like unto treasure hid in a field; the which when a man hath found, he hideth, and for joy thereof goeth and selleth all that he hath, and buyeth that field.

Jesus then begins a series of three short parables which were directed at the disciples. The first one in this verse speaks of a treasure which is hid in a field. In ancient times, one who had much wealth had to do his best to hide those valuables from thieves because there were no banks or any other type of place he could keep his valuables from being stolen. This was also done during wartime when valuables like payrolls were hidden to keep them from falling into the hands of the enemy, especially if it was gold because it could be melted and coined in the denominations of the enemy. Normally the one who would find the treasure in a field would be the laborer and then he would hide the treasure in a different place. In this parable, the field is the world and the hidden treasure is the Elect of God. For the Elect of God to be saved, there would have to be a substitute to pay for their sins. The one who bought the field was the Lord Jesus Christ who paid for it with His own blood on Calvary. He came down from Heaven and gave all He had, that was His life and purchased the field. Under Jewish law, if a person bought a field, they were also entitled to everything which was in that field. If they found treasure, it was theirs by law. The Lord Jesus bought the field of the world and within the world are the Elect of God which are scattered from one corner of earth to the other.

Mat 13:45 (KJB)
Again, the kingdom of heaven is like unto a merchant man, seeking goodly pearls:

Then Jesus likens the Kingdom of Heaven unto a merchant man or as we would call him a businessman. His desire is to seek cultured, valuable pearls. This scenario would also have been familiar to the people because pearls were recovered in the Indian Ocean, Red Sea, and the Persian Gulf. Pearls were sometimes worth a lot of money so this man was undoubtedly a wealthy business man whose business was pearls and precious gems.
