And those duped by satan have fallen for it, and will be joining him in the Lake of Fire for eternity (Revelation 20:10-15). Scripture is quite clear that not everyone is going to be saved, and that those who are unsaved are in the majority, whereas the saved are relatively few:
"Enter ye in at the strait gate: for wide is the gate, and broad is the way, that leadeth to destruction, and many there be which go in thereat: Because strait is the gate, and narrow is the way, which leadeth unto life, and few there be that find it"
Universalism is nothing by a lie, and those promoting it are liars and deceivers and will not be found in Heaven nor in the New Earth (Revelation 22:15).

"Some bring God's curse on them by marking off part of the Bible, calling it erroneous, uninspired, less than the very Word of God."
- Dr. John R. Rice
"For I am not ashamed of the gospel of Christ: for it is the power of God to salvation to every one that believes; to the Jew first, and also to the Greek."
