Have a sincere desire to serve God and mankind, and stop doubting, stop thinking negatively. Simply start living by faith, pray earnestly and humbly, and get into the habit of looking expectantly for the best. When you live on a faith basis your desire will be only for that which you can ask in God’s name. By success, of course, I do not mean that you may become rich, famous, or powerful. I mean the development of mature and constructive personality.
Norman Vincent Peale
“Peace I leave with you; my peace I give to you. Not as the world gives do I give to you. Let not your hearts be troubled, neither let them be afraid.”
