Every new year, many of us hang a new calendar on the wall, with a calendar that has no marks except for the special holidays that are printed in the calendar. And it remains to be filled in with events that have not yet occurred, many of which are totally unexpected. So it is with the future. We simply do not know what tomorrow holds. In fact, we don't know what this afternoon holds, to say nothing of next month or next year. There are days we wish we knew. There are other times we're glad we don't. As we face an unknown future, let's examine what 1 Thessalonians 4:13-18 teaches us about our greatest hope.
