In the Book of Mormon, Alma says,
45. And now I say unto you, my beloved brother Moroni, that never had I seen so great courage, nay, not amoungst all the Nephites.
46. For as I had ever called them my sons (for they were all of them very young) even so they said unto me: Father, behold our God is with us, and he will not suffer that we should fall; then let us go forth: we would to slay our brethren if they would let us alone; therefore let us go, lest they would overpower the army of Antipus.
47. Now they never had fought, yet they did not fear death; and they did think more upon the liberty of their fathers than they did upon their lives; yea, they had been taught by their mothers, that if they did not doubt, God would deliver them.
48. And they rehearsed unto me the words of their mothers saying: We do not doubt, our mothers knew it.
Mother, I doubt not because you know it.
I love you.
