Revelation 12 shows Satan kicked out of heaven and cast to the earth where he persecutes the church and individual Christians, but the earth helps the people of God.
That infuriates Satan and so he brings up from the earth, the sea in particular, a helper who will persecute the church mightily,
“Then he opened his mouth in blasphemy against God, to blaspheme His name, His tabernacle, and those who dwell in heaven. It was granted to him to make war with the saints and to overcome them. And authority was given him over every tribe, tongue, and nation” (Revelation 13:6-7).
The Roman beast did all it could with the power of Satan to destroy the church, but Rome failed, and the church prevailed!
Do not let the powers of this earth frighten you, but know that greater is He who is on our side than he who is on the other side.
