“The kingdom of heaven is like a treasure hidden in the field, which a man found and hid again; and from joy over it he goes and sells all that he has and buys that field.” Matthew 13:44 (NASB)
Jesus Christ is the true treasure; in Him there is an abundance of all that which is rich and useful, and will be a portion for us: all fullness (Col. 1:19; John 1:16): treasures of wisdom and knowledge (Col. 2:3), of righteousness, grace, and peace; these are laid up for us in Christ; and, if we have an interest in Him, it is all our own. Matthew Henry
What is the world to me,
With all its vaulted pleasure
When Thou, and Thou alone,
Lord Jesus, art my Treasure!
