Your attitude should be the same as that of Christ Jesus.” To have Christ’s attitude we must have His mind, which will only come from His Word.

• "Whatever you hold in your mind will tend to occur in your life. If you continue to believe as you have always believed, you will continue to act as you have always acted. If you continue to act as you have always acted, you will continue to get what you have always gotten. If you want different results in your life or your work, all you have to do is change your mind."
  I don’t know who wrote this, but it’s a great quote. The key to any kind of improvement in life is in the mind. The thinking controls the actions.
