People don't look too far ahead ~ they only look forward to attending events scheduled for the coming days one by one. For example, I have noted on my calendar such events as our church's pancake breakfast, funeral service of a friend, dental checkup, grandson's graduation from junior hi next month, etc. We are truly here today and gone tomorrow. No one knows when that tomorrow (or last moment) will be. The most important thing is to look far ahead to see where we are going. If we know our destination, then we do longer live from event to event, for the events are like receding telephone poles we see from a moving train as we travel toward our final destination. There is no comparison between knowing that you'll arrive safely at the end and not knowing when train might crash along the way.
