nHebrews 12:1-3, 12-13 pictures life as a long-distance race.
So old age is the final lap.
nThe book of Job (chapters 1-2) gives us a hint here also, with its picture of what is going on behind the scenes.
nOur last challenge is to finish our race well, though this challenge may be invisible to most other people.
nYet the angels are watching!
