[Sennacherib] wrote also letters to rail on the Lord God of Israel, and to speak against Him.
This is folly. Sennacherib was not a smart man. Satan was using this man to cause God’s people to doubt His ability to save them. Satan is doing the same thing today. He continually sows doubts in our minds to make us question the goodness and faithfulness of God. Do not listen. Control and reject any thought that doubts God or your salvation through the Lord Jesus Christ.
