Treasure or Peculiar treasure is another scripture defined word that is ignored or not understood.
Matthew 13:44 “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.”
The word treasure or peculiar treasure is defined by scripture.
Psalms 135:4 “For Yahweh hath chosen Jacob unto himself, and Israel for his peculiar treasure.”
Christ stated His purpose.
Matthew 15:24 “But he answered and said, I am not sent but unto the lost sheep of the house of Israel.”
Did Christ fail? It is only because the world has the wrong people as Israel that churches teach Christ failed in His purpose. Believe the scripture, question the world.
