To be God’s property mean that we are owned by God. There is a powerful story about an English missionary whose house was being looted. “An English missionary died in the early part of this century [the 20th century]. Immediately after his death his former neighbors broke into his house and started carrying away his possessions. The English Consul was notified, and since there was no lock on the door of the missionary’s house, he pasted a piece of paper across it and affixed the seal of England on it. The looter did not dare break the seal because the world’s most powerful nation stood behind it.”  To be sealed means that we are God’s property!
