Your thought patterns determine your ability to break bad habits.
Philippians 4:8 (NKJV)
Finally brethren, whatever things are true, whatever things are noble, whatever things are just, whatever things are pure, whatever things are lovely, whatever things are of good report, if there is any virtue and if there is anything praiseworthy – meditate on these things.
The key to victory over bad habits is refocusing your thoughts, not resisting negative thoughts. Resisting negative thoughts forces you to focus on the very thoughts you are trying to resist. Resisting negative thoughts actually reinforces bad habits. Focusing on any thought, positive or negative, reinforces the related habit. You can break an old bad habit by creating a new good habit. Once your thoughts focus on the new habit, the old habit starts to fade away. Replace your old bad habit caused by negative thoughts with a good habit caused by positive thoughts.
Your mind will always be occupied with thoughts. You can discontinue a thought by replacing it with another thought. Whatever you focus on will tend to increase in your life. The more you think about something, positive or negative, the more the outcome of that thought will be attracted into your life. This new way of positive thinking will allow you to enjoy the victory that God has already provided for you.
You can apply the principles in God’s Master Success Book to your life by replacing negative thought patterns with positive thought patterns. Replace negative thoughts with positive thoughts of who you are in Christ. Change the way you think to become what you want to be. Make a conscious effort to fill your mind with thoughts that are true, honorable, right, pure, lovely, and admirable. Think about things that are excellent and worthy of praise. Keep your mind filled with Philippians 4:8 thoughts. This is the way to effortlessly break bad habits.
