The author of Hebrews challenges his original audience to “run the race with endurance” and to cast aside those things that will slow them down. And while we may not be tempted to return the Mosaic Law as they were, we too are called to “finish our race” by keeping the faith. 
As some readers may know, when I am not reading a theology book or hanging with the family I can be found working out for an upcoming race. A race that often involves mud and obstacles. As in any race, we can start off well, but fail to reach the finish line if we become sluggish in our training and fail to keep our eyes focused on the finish line.
This truth about running races was an analogy used by Paul (1 Cor 9:24-27; 2 Tim 2:5) as well as the author of Hebrews (12:1) to describe the Christian life. Both Paul and the author of Hebrews were afraid of running the race in vain (Gal 2:2) even if they started off well (Gal 5:7) because they did not want to fail to receive what was promised (1 Cor 9:27; Heb 10:35-36). This motivated them to press on and strive to reach their goal (Philippians 3:14; Heb 4:11) so that they could reach that finish line (2 Tim 4:7) and exclaim:
I have finished the race, I have kept the faith.
And they encouraged others to do the same.
