Jesus said, “The kingdom of the Father is like a merchant who had a load (of goods) and found a pearl. That merchant was wise. He sold the load and bought for himself the pearl alone. You also, seek after his treasure which does not fail (but) endures, where moth does not come to eat nor worm to destroy.”
As familiar as this saying is to those of us who have read the Synoptic Gospels of the New Testament, the essential meaning of this parable in Thomas is quite similar to those, but with a slightly different application.
In both Matthew and Luke, the parable is merely about the incalculable worth of the Kingdom as compare to the riches of this world and the instruction is for us to give up our worldly possessions – which rust and fade – to acquire the Kingdom of God which endures forever.
