A Challenge to the Traditional View of the Beast of Revelation
The traditional view of the Beast of Revelation, as I understand it, is that the Beast is the personification of the antichrist.  The seven heads, as I understand, are synonymous with seven of the horns after three of the ten have been plucked up or subdued.
Here is the common grace interpretation of the beast of Revelation as has been taught to me by many grace preachers:
Revelation 13:11-12, “And I beheld another beast coming up out of the earth; and he had two horns like a lamb, and he spake as a dragon.  And he exerciseth all the power of the first beast before him, and causeth the earth and them which dwell therein to worship the first beast, whose deadly wound was healed.”

 Paul, called to be an apostle of Jesus Christ through the will of God, and Sosthenes our brother, Unto the church of God which is at Corinth, to them that are sanctified in Christ Jesus, called to be saints, with all that in every place call upon the name of Jesus Christ our Lord, both theirs and ours: Grace be unto you, and peace, from God our Father, and from the Lord Jesus Christ. I  Corinthians 1:1-3

In the passage of Scripture quoted above Paul tells us that believers in the Age of Grace are “sanctified . . . called to be saints”.  The names and titles by which God identifies an individual or group give us great insight into the role that that person or group plays in God’s plan and purpose.
