John 8:24 (KJV): “I said therefore unto you, that ye shall die in your sins: for if ye believe not that I am he, ye shall die in your sins.”
John 8:24 is a quotation of something that Jesus said.
One of the big things I love about being Catholic is that not everything is about “FIRE AND BRIMSTONE, YOURE GOING TO HELL!!!” While he’s, there’s a process and organization, it’s an incredibly accepting group. You may disagree with someone’s choices and thoughts, but you’re never supposed to actually hate someone. In the end, even while there are requirements to officially join the church, it’s generally understood that as long as you’re a good person with an idea of god, it’s up to him.
