As believers, we often look forward to that day we call "The Day of the Lord," but Amos says we might not be so happy when it comes. "Alas, you who are longing for the Day of the LORD, for what purpose will the day of the LORD be for you? It will be darkness and not light." Is this only true for those who don't believe in Jesus? First Corinthians 3:13-15 suggests it might not be so pleasant for believers, also.
