Discipline of yourself is absolutely necessary before the power of God (as you may know him/her) is given to you. When you see others manifesting the power of God, you probably have not seen the discipline that went before. They made themselves ready. All your life is a preparation for more good to be accomplished when God knows that you are ready for it. So keep disciplining yourself in the spiritual life every day. Learn so much of the spiritual laws that your life cannot again be a failure. Others will see the outward manifestation of the inward discipline in your daily living.
