That is why I said you will die with your sins unforgiven. If you don't have faith in me for who I am, you will die, and your sins will not be forgiven.”
Make sure that you obey the one who speaks to you. The people did not escape, when they refused to obey the one who spoke to them at Mount Sinai. Do you think you can possibly escape, if you refuse to obey the one who speaks to you from heaven?
So if we refuse this great way of being saved, how can we hope to escape? The Lord himself was the first to tell about it, and people who heard the message proved to us that it was true.
