"I should not have known"

1. 1 Ne. 5: 4
     4 And it had come to pass that my father spake unto her, saying: I know that I am a visionary man; for if I had not seen the things of God in a vision I should not have known the goodness of God, but had tarried at Jerusalem, and had perished with my brethren.
2. Alma 36: 5
     5 Now, behold, I say unto you, if I had not been born of God I should not have known these things; but God has, by the mouth of his holy angel, made these things known unto me, not of any worthiness of myself;
3. Alma 38: 6
     6 Now, my son, I would not that ye should think that I know these things of myself, but it is the Spirit of God which is in me which maketh these things known unto me; for if I had not been born of God I should not have known these things.
