Matthew 13:44-46: "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."
The Kingdom is PRECIOUS
Lives are given in the pursuit of hidden treasure & fine pearls.
The gates of the new City of God in Revelation are made of pearl.
