The Day of the Lord refers to the second coming of Jesus Christ. Does the fact that Paul (and most Christians of that time) believed that Jesus was “coming soon,” plus the fact that Jesus, in fact, did not come in their lifetimes, damage the authority and infallibility of the Scriptures? I don’t think so. Though, it would be difficult to convince a skeptic. I think it’s the hope of every single Christian to witness the second coming; every Christian wishes that Jesus would return in his lifetime. Maybe it’s the fear of death, but in every time period, there have been those who believed “the end was near.” Even I think the end could very possibly be near. I’m not into interpreting prophesies or anything, but now’s as good a time as any! Paul simply shows his humanity in his hoping that the Day of the Lord was near. He was never dogmatic in declaring it to be an absolute truth.
