What happens to you if you die in a state of mortal sin (persistently unrepentant)?
You will receive punishment in hell eternally, forever and ever. It is that serious!
In 1917 at Fatima Portugal, the Mother of God appeared to 3 children and showed them a vision of hell. She didn’t think that Francisco, age 9; Jacinta, age 7; and Lucia, age 10, were too young to learn about the reality of eternal death.
Can you see that a person is in a state of mortal sin?
Mortal sin is not visible to our natural eyes.
However, the impacts of mortal sin may be visible to us and others.
For instance, a person in mortal sin may become physically or emotionally sick.
Also, such a person is likely to show the bad state of his soul by repeating serious sins such as lying, cheating, stealing, committing adultery, killing or cursing God.
