Likutei Moharan 7:2/ליקוטי מוהר"ן ז׳:ב׳

12. Yet it is impossible to come to faith except through truth. As is brought in the Zohar (III, 198b): “And justice will be a belt for his hips, and faith a band for his loins” (Isaiah 11:5). What then is the difference between justice and faith? The answer given there is: [justice] is called faith when it is bound with truth.
