I have trained for and run four marathons. I literally have run thousands of miles in my thirty years of running. The best physical condition I have ever been in was during the 18 weeks of training for each of those long runs. The fact is I have not run in more than a year and a half---and my past accomplishments do nothing for me today. Yesterday's training is a thing of the past and left no lasting impact on me today. Unless I am willing to begin again and build for the future---the past is exactly that--in the past.
How many of us think---I have done my part---been there and done that--now it is time for someone else to step up to the plate. I served my church, taught Sunday School, cooked dinners, did more things to serve than I can remember. I am at retirement age--so it is my time to rest. I served on civic committees, belonged to civic clubs, worked for my community--but now I am retired and there are younger professionals who should step up and take the mantle while I play golf/tennis. I spent years helping the homeless, the struggling, the poor, the disadvantaged, but that time has now past.
If our spiritual health shadows our physical health---what we did in the past--is just that--in the past. What we did yesterday to further The Kingdom--to glorify The Creator is wonderful---but what have I done today? He has not stopped blessing us--the fact we are now considered seniors does not stop the steady flow of His blessings. There is no reason as long as we are physically able to quit---we may not be as fast--we may not be as strong---but we can still run the race.
Therefore, since we are surrounded by such a huge crowd of witnesses to the life of faith, let us strip off every weight that slows us down, especially the sin that so easily trips us up. And let us run with endurance the race God has set before us.
