There are two kinds of discipline: 1) self imposed, 2) imposed by others. The second is virtually useless. The teacher, coach, parent, judge punishes the infractor, who supposedly repents and redirects his life. Instead, he resents and seethes.
But the first is the maker of every greatness: athletes, inventors, successful people, ministry leaders. We may be saved by grace through no self work, but we become heroes through much work. We advance God’s kingdom through much work.
Don’t wait for God to discipline you. It will be unpleasant. Discipline yourself. Salvation is free and easy. But doing good and getting blessings from are the product of effort. Without self-discipline 
incalculable potential is only wasted. Unleash your dynamism today. People will marvel at your impact. You’re destined for greatness but it remains unseen because of lack of discipline.
Discipline yourself to pray. Discipline yourself to Bible study, to church attendance, to fellowship.
Without discipline, Joseph’s dreams would have remained only dreams. Without discipline, Elijah’s vision for apostate Israel never would have sparked revival. I beat my body and make it my slave so that after I have preached to others, I myself will not be disqualified for the prize. — 1 Cor. 9:27 NIV.
