1 Cor 9:27 But I discipline my body and bring it into subjection, lest, when I have preached to others, I myself should become disqualified.
If I wanted to run a marathon I would need to get into shape.
I would need to get up every morning and work out with some walking, weight lifting, and a diet that supports my desire to run a marathon.
I would have to build up my endurance and stamina to where I could run a few laps, eventually to a mile, then five, and on to ten, and so on.
I will need to discipline my body to keep going because, although my mind wants to run, my body wants to stop.
I want to stay in bed.
I don’t want to get up and work out anymore.
I understand that even when you are in top physical condition, you’re body will try to tell you to stop during such a long run.
Your mind must tell your body to keep going, keep pushing forward, and reach the finish line.
In Christianity, it is much the same as your flesh and mind war against your spirit.
This is the reason Paul said he disciplined his body to bring it into subjection.
I know how difficult it is to read the Bible every day.
Going to church every Sunday and Wednesday gets old when there are so many other things that need your attention.
This is where you must discipline yourself to press on and reach toward the goal for the prize of the upward call of God in Christ Jesus.
