Again, the kingdom of heaven is like unto treasure hid in a field; the which when a man hath found, he hideth, and for joy thereof goeth and selleth all that he hath, and buyeth that field. – Matthew 13:44
the treasure = believers, the body of Christ, the Church (not the buildings)
the field = the world, the creation
the man = Jesus
The kingdom of heaven is like the Church in the world; the which when Jesus predestined, He hid from the Old Testament, and then came into His creation to willingly give all that He had, and die on the cross to redeem His Church and Creation.
Jesus has bought us and the creation back with the blood He shed on the cross, and He will take final possession, with us following, after He finishes opening the seven sealed title-deed He takes out of the right hand of the Father. – Revelation 5:1, Revelation 5:7
