If you want to dismiss a negative thought, the only way to do so is to think of something positive and constructive.
Emmet FoxHere's an experiment: For one whole day think, speak, and act exactly as you would if you were absolutely convinced of the truth of the statements that God has all power and infinite intelligence, and that His nature is infinite goodness and love. To think in this manner all day will be the most difficult thing, because thought is so subtle. To speak in accordance with these truths will be easier, if you are vigilant. To act in accordance with them will be the easiest part, although it may require much in the way of moral courage.
Emmet FoxThe present moment is never intolerable. It is always what is coming in five minutes or five days that makes people despair. The Law of Life is to live in the present, and this applies to both time and place. Keep your attention to the present moment, and in the place where your body is now. Do a fair day's work, and then stop. Overwork is not productive in the long run.
Emmet FoxGod is bigger than any problem. God in you is greater than any difficulty you have to meet. God cares for you more than it is possible for any human being to realize. God can help you in proportion to the degree in which you worship him. You worship God by really putting your trust in him instead of in outer conditions, or in fear, or in depression, or in seeming dangers, and so forth. You worship God by recognizing his presence everywhere, in all people and conditions that you meet; and by praying regularly. You pray well when you pray with joy.
