Jesus taught us a simple way of knowing who to trust and follow: "You will know them by their fruits." Some fruits of the Spirit would be: consistent peace and happiness, transparency, and a true generosity that gives freely of the heart. One's attitude is the greatest demonstration, and it is important that one doesn't just "talk the talk" but also "walks the walk." We all have the truth within us, and so by tuning into our feelings, we will be Guided as to who or what to follow, moment by moment . . .
