Let us run the race that is before us and never give up. Hebrews 12:1
The word race is from the Greek agon, from which we get the word agony. The Christian's race is not a jog but rather a demanding and grueling, sometimes agonizing race. It takes a massive effort to finish strong.
Likely you've noticed that many don't? Surely you've observed there are many on the side of the trail? They used to be running. There was a time when they kept the pace. But then weariness set in. They didn't think the run would be this tough…
By contrast, Jesus' best work was his final work, and his strongest step was his last step. Our Master is the classic example of one who endured… He could have quit the race. But he didn't.
