Universalism teaches that all people will eventually be saved through the atonement of Christ. It says that all mankind, even those who have openly rejected Jesus, those who have willingly committed horrible crimes and died without repentance, and without the covering of Christ's blood, will enjoy a future with God. This belief is based upon the idea that God's love is so infinitely great, that His grace in Christ is so awesome, that everyone will be saved. This simply is not true.
The danger of universalism is that it to can give someone a false sense of security about their eternal destiny. It can remove the need of accountability. It can remove the fear of judgment. It does not require repentance. A person who adopts universalism can easily conclude that if he is going to be saved no matter what he does, then why be concerned about repentance or accepting Jesus as Lord and Savior? This potential error is most dangerous. Especially because if universalism is not true, then the false sense of security it has given to those who have not trusted in Christ, will lead them to ****ation. This is a very serious danger.
Of course, simply because it is possible that people will become lax in accepting Christ if they adopt universalism, it does not mean this is what will happen. Nor does it mean that all Universalists think they can go out and sin willfully. On the contrary, most Universalists are very moral. But, there is the inherent danger in universalism that reduces the need for repentance and salvation. This is a great risk. Eternity is a long time to be wrong and hell is a terrible place to be forever.
