Jesus and his apostles (the real ones) gave a clear picture of societal and cultural conditions which believers would experience in the times before Jesus' return. Some like to point out that New Testament references of the "last days" or "the day of the Lord" are referring to the entire time period from the resurrection of Christ, or from Pentecost onwards. We've always been in the "last days" they say. In a way that's true, but there's more to come. Go to any passage of Scripture where someone is speaking of end times things and you'll find they're speaking of the future, not their own time.
