These are just a few of the many verses that refute Universalism and "everybody goes to Heaven" but really there are many more I could list here from all over the Bible, the scripture is clear when you take the time to read it that not everyone will be saved. Universalism contradicts Jesus Christ. Anyone who thinks that everyone will be saved is clearly misinterpreting scripture and the message of Jesus Christ and what he did on the cross. This is a very wicked and unbiblical false teaching and spiritual attack on all believers of Jesus.
