153. How did Jesus explain that something extremely valuable is offered in the kingdom of God?

The parable of the pearl of great price showcases those individuals who recognise the wealth hidden in Jesus Christ, accept it, and give up everything else just to have it. In another passage, Jesus underlines this with the admonition: “But seek first the kingdom of God...”
(Matthew 6: 33).

“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 and buys that field. 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.” Matthew 13: 44-46
“But seek first the kingdom of God and His righteousness, and all these things shall be added to you.”
Matthew 6: 33
