If you have a long drawn out face and are feeling depressed, you have a millisecond to decide to agree with God. Practice the presence of the Lord. Change the fuel that drives the mind and you will change the experience of everything you are trying to accomplish. You will either be resourceful or un-resourceful based on the habit of the emotion that you most often use.
Once you realize you are in control of the fuel that directs your thoughts, words, and actions then the next step is recognizing the power of decision that you make from moment to moment throughout the rest of your life. Remember, you do not have a need; you have undiscovered resources. The power of God is available to you to bring you into a God-class.
