The Sealing Finger of God is The Holy Spirit, Grieve him not, Nor Strive, Noah Flood and Science

And the LORD said, My spirit shall not always strive WITH MAN, for that he also is flesh: yet his days shall be an hundred and twenty years.
Genesis:6:3

Know ye not that ye are the temple of God, and that the Spirit of God dwelleth in you? If any MAN DEFILE the TEMPLE OF GOD, him shall God destroy; for the temple of God is holy, which temple ye are. For the wisdom of this world is foolishness with God. For it is written, He taketh the wise in their own craftiness. And again, The Lord knoweth the thoughts of the wise, that they are vain.
1 Corinthians:3:16-17,19-20

Then the magicians said unto Pharaoh, This is the finger of God: and Pharaoh’s heart was hardened, and he hearkened not unto them; as the LORD had said.
Exodus:8:19
