SATAN'S PLAN OF VENGEANCE AFTER THE CROSS.

By the death of Christ, Satan knew that his own final destruction was certain and that the kingdoms of this world would ultimately be given to Jesus.

Having failed to overcome the Son of God, Satan gathered his angels in council and determined to direct all their power, hatred, and cunning against Christ’s followers.

They would seek to prevent as many people as possible from receiving the salvation purchased for them through the blood of Jesus. Through persecution, deception, compromise, and the introduction of false doctrines, Satan gradually corrupted apostolic Christianity, developing it into the powerful Roman Catholic religious system. Many of her false teachings were later adopted and carried forward by the apostate Protestant churches that came out of Rome but failed to separate completely from her doctrines and traditions.

He would encourage professed Christians to retain the name of Christ while rejecting His authority, His commandments, and the transforming power of His gospel.

In this way, Satan could continue his rebellion against the government of God and keep as many souls as possible from Christ and His gift of salvation.

It was also in Satan’s own interest to prevent people from accepting salvation. The sins of those who are redeemed by the blood of Christ will finally be placed upon Satan (the scapegoat), the originator and instigator of sin, and he must bear the consequences of his rebellion. But those who refuse the salvation offered through Jesus must suffer the penalty of their own sins.

The great controversy did not end at the cross. At the cross, Satan’s defeat was made certain—but from that moment onward, his warfare against Christ and His followers became even more determined.
