Self-control opens up the possibility of greatness.
The absence of self-control has the power to ruin your life.
Solomon wrote in Proverbs 25:28, "A person without self-control is like a city with broken-down walls."
In the ancient world a city without walls was completely unprotected and susceptible to enemies. People would be living in distress waiting for disaster to come upon them. It wasn't really a question of if the enemy would come it was more a question of when. One of the greatest leaders in the Bible is Nehemiah. He is deeply concerned when he hears that Jerusalem's walls were destroyed and the Jews were unprotected. Nehemiah is so concerned he "sat down and wept and mourned for days, and continued fasting and praying before the God of heaven." He is known forever for rebuilding Jerusalem's walls.
To live without walls is dangerous and should be taken extremely serious. If your walls have broken down and you find yourself lacking self-control - it is time to rebuild.
Say no to yourself at least once a day.
This will begin to develop the discipline necessary to choose correctly in the midst of temptation. You may be saying no to french fries, alcohol, fast driving, checking twitter every minute, your 4th Starbucks of the day - say no to something it is good for you.
