Beginning well is a momentary thing; finishing well is a lifelong thing.
Many of us have begun well but finished poorly in our attempt to diet or exercise. Usually, we begin with a lot of excitement and anticipation. But, when the effort becomes tedious and the obstacles mount, it’s so easy to find a better option and just bailout. Finishing well demands good intentions and perseverance; it may take a long time.
I have fought the good fight, I have finished the race, and I have remained faithful. (2 Timothy 4:7)
