The Parable of the Hidden Treasure (Matthew 13:44)
“Again, the kingdom of heaven is like treasure hidden in a field, which a man found and hid; and for joy over it he goes and sells all that he has buys that field.
The Parable of the Pearl of Great Price (Matthew 13:45)
Again, the kingdom of heaven is like a merchant seeking beautiful pearls, who, when he had found one pearl of great price, went and sold all that he had and bought it.
These two parables have identical meanings. Both picture salvation as something hidden from most people but so valuable that people who have it revealed to them are willing to give up all they have to possess it.
Parable of the Dragnet (Matthew 13:47-50)
“Again, the kingdom of heaven is like a dragnet that was cast into the sea and gathered some of every kind, which, when it was full, they drew it to shore; and they sat down and gathered the good into vessels, but threw the bad away. So it will be at the end of the age. The angels will come forth, separate the wicked from among the just, and cast them into the furnace of fire. There will be wailing and gnashing of teeth”.
Some fishing was done with a large weighted net dragged along the bottom of the lake. When pulled in, it contained an assortment that had to be separated. In a similar way the visible kingdom, the sphere of those who claim to be believers, is full of both good and bad and will be sorted in the judgement. The angels serve God in judgement. (2 Thessalonians 1:7-10)
Parable of the Householder. (Matthew 13:51-53)
Jesus said to them, “Have you understood all these things?” They said to Him, “Yes Lord.” Then He said to them, “Therefore every scribe instructed concerning the kingdom of heaven is like a householder who brings out of his treasure things new and old”.
The disciples were not told to spurn the old for the sake of the new. Rather the new insights they gleaned from Jesus’ parables were to be understood in light of the old truths, and vice versa.
