Jesus compared The pearl of great price to show the value and importance of the kingdom of heaven, as treasure hidden in a field, and a fishing net to the Kingdom of Heaven where people would be gathered up and then sorted out and separated. He tells us angels will come and separate the good from the bad and the bad will be thrown away. When Jesus spoke in parables he often said, "Who hath ears to hear, let them hear" because He only wanted God's chosen to hear and understand what it is He was trying to convey. Meaning that whoever pays attention to His words can understand the true meaning.
Then shall the righteous shine forth as the sun in the kingdom of their Father. Who hath ears to hear, let him hear. Matt. 13: 43
Jesus compared the kingdom of heaven to a treasure hidden in a field and when a man finds it he will give up everything he has and buy that field. When you get saved, you know in your heart that by doing God's will you will get the opportunity to go to heaven. However, you must be willing to give up all that is standing in the way of you and your relationship with God in order to get the opportunity to go to heaven and be with the Lord. This means things like cars, homes, clothes, relationships, habits, etc. This doesn't mean you cannot have these things or people in your life. It does mean that if any one of them prevents you from spending time praying and reading the word of God then you need to get them out of your life. If you have people in your life that are keeping your from doing God's will then you need to help them get saved or get away from them. If material things or habits distract you from doing God's will then you need to change the way you think or the things you do so that you can get your life in line with God's word.
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. Matt. 13:44
Merchants sought good pearls because they fetch a good price and could make them rich. The Kingdom of Heaven is compared to a man searching for these precious pearls. When the man found one precious pearl he sold everything he had to get the money to buy the pearl. Does this mean we can buy our way into the kingdom of heaven? No. It does mean that Heaven is more precious and worth more than any amount of money.
Again, the kingdom of heaven is like unto a merchant man, seeking goodly pearls: Matt. 13:45
When the man found a good pearl of great price, he knew he simply had to have it. He wanted the pearl so much that he gave up all that he owned just to get it.
Who, when he had found one pearl of great price, went and sold all that he had, and bought it. Matt. 13:46
Then Jesus compared the Kingdom of heaven to a net, cast into the sea to catch fish of every kind which indicates that people of all nationalities, lifestyles, and backgrounds can go to heaven.
Again, the kingdom of heaven is like unto a net, that was cast into the sea, and gathered of every kind: Matt. 13:47
Not everyone who hears God's word will be able to get into heaven. Jesus tells of how they will sort through the fish, keep the good ones and throw the bad ones away.
Which, when it was full, they drew to shore, and sat down, and gathered the good into vessels, but cast the bad away. Matt. 13:48
Jesus tells us that in the end of the world the angels will come and sort through the people, separating the good ones from the bad ones.
So shall it be at the end of the world: the angels shall come forth, and sever the wicked from among the just, Matt. 13:49
The bad people will be thrown away by being put into a furnace of fire where there will be wailing and gnashing of teeth.
And shall cast them into the furnace of fire: there shall be wailing and gnashing of teeth. Matt. 13:50
After Jesus told the parable of The Pearl of Great Price He asked them if they understood what he meant and they responded that they did indeed understand the meaning of the parable.
Jesus saith unto them, Have ye understood all these things? They say unto him, Yea, Lord. Matt. 13:51
Everyone who is called by God to teach His word is held responsible to bring the things that they treasure the most to God.
Then said he unto them, Therefore every scribe which is instructed unto the kingdom of heaven is like unto a man that is an householder, which bringeth forth out of his treasure things new and old. Matt. 13:52
And it came to pass, that when Jesus had finished these parables, he departed thence. Matt. 13:53
If you are not saved you need to get saved unless you don't care if you get thrown out.
If you are saved you need to make sure that you put nothing in your life before Him (not family, friends, or material things). You must make your thoughts, words, and actions line up with the perfect will of God. You need to pray and study every day to make sure that you do not stray.
