“And it was commanded them that they should not hurt the grass of the earth, neither any green thing, neither any tree; but only those men which have not the seal of God in their foreheads.”
Seal is the word Sphragis
There is a lot of meaning lost in this. Sphragis
We are Gods property and signed for the package with His signature….. The Holy spirit
We can never lose His signature but we can grieve Him.
So we should know if we are sealed or not and not worry about what marks the devil wants to play with.
