their testimony was like fire in my bones...(Brigham Young)
The brethren who came to preach the Gospel to me, I could easily out-talk them . . . ; but their testimony was like fire in my bones; I understood the spirit of their preaching; I received that spirit; it was light, intelligence, power, and truth, and it bore witness to my spirit, and that was enough for me.
