The concept of universalism is not taught in the Scriptures. It's a man made doctrine to appeal to the flesh. The reality of eternal damnation is tough to swallow, but it is what is taught in the Scriptures.
Jesus speaking.
Matthew 5
27 You have heard that it was said to those of old, 'You shall not commit adultery.'
28 But I say to you that whoever looks at a woman to lust for her has already committed adultery with her in his heart.
29 If your right eye causes you to sin, pluck it out and cast
it from you; for it is more profitable for you that one of your members perish, than for your whole body to be cast into hell.
30 And if your right hand causes you to sin, cut it off and cast
it from you; for it is more profitable for you that one of your members perish, than for your whole body to be cast into hell.
Jesus is teaching the crucial fact that we must get the sin out of our lives or face damnation in hell.
